The only real issue is the level of formality or politeness of the discussion. (Even then, "OK" is usually fairly acceptable in spoken conversations even when things are reasonably formal. It's often not used as much in formal written conversation, though.)
If someone asks you a question online or over text, do not respond with “OK.” or “Yes.” You might use “sure” or “yep” without punctuation; you should probably add an exclamation mark. Otherwise you might sound passive aggressive, dismissive, or angry. There's a good reason for this.
You don't need to respond when somebody says ok just leave it on read or like the message instead. I think that non-verbal clues are very important. And tone of voice. But I would ask specific questions to get more details.
OK (/ˌoʊˈkeɪ/ ( listen); spelling variations include okay, O.K., ok and Ok) is an English word (originating in American English) denoting approval, acceptance, agreement, assent, acknowledgment, or a sign of indifference. OK is frequently used as a loanword in other languages.
Most historians agree that OK stands for "all correct," which is why we use the word to express agreement, approval or just as a way of saying that everything is fine. The shorthand expression came about during the late 1830s, when it became popular to use abbreviations rather than entire terms during conversations.
OK is one of the most common slang terms; often used to communicate approval, agreement, acceptance, or acknowledgment.
We use okay as a response token to show that we understand, accept, or agree with what someone is saying: … We often use okay as an adjective to say that something is not a problem, it's 'all right': …
The Word 'O.K.' Has Just Celebrated Its 177th Birthday
Here's first appearance of the word 'ok' took place on March 23, 1839, as Atlas Obscura writes today: “We said not a word about our deputation passing “through the city” of Providence.
Ok : she is having a casual feeling like a friend for you. Okkk: she is interested in you , she wants to know more about you and want to spend more time with you.
AVOID sending one word replies like 'OK' or 'YES' or 'NO' whenever you can. Some times, one word replies can be perceived as being rude. Instead, just try saying, 'OK, name of the sender' or 'Yes, sounds good' for example. Again, just a couple of extra seconds will not hurt you.
Reply within 30–60 minutes to play it a little cool.
While it's okay to reply later if you're actually busy, purposefully waiting to text somebody might feel disrespectful if you're available. If you had to make the person wait for more than an hour, offer them an apology and explain what kept you from messaging them.
The most straightforward way to pretend that you're angry over text is to use mean or aggressive language to get the point across. Whether you insult the person, criticize them, or clearly state that you are angry, being hostile is the most unmistakable way to express anger.
Reframe the question.
It might be easier to respond to a different type of question: I find “How are you feeling right now?”, “What's on your mind?”, “How has your day been so far” are all smaller and easier to wrangle than “Are you OK”. I'll try to reframe the original question in to something I can tackle.
I think the OED's definition of Okay clarifies this nicely. It says "Expressing assent, concession, or approval, esp. with regard to a previous statement or question: yes, all right." So it is only in the sense of expressing approval that okay and yes mean the same thing. Other meanings of yes are not included.
Should You Use OK or Okay in Formal Writing? As above, these spellings are both fine. Neither is more “formal” than the other. And the choice between them is a matter of preference, so just use whichever version you like more.
Saying "OK" instead of an outright "Yes" to a question or request is noncommittal. It gives the sense of cooperation without revealing the speaker's personal opinion on the matter.
If the text contains personal, emotional stuff, then “OK” is going to sound dry and uncaring. Not every case is the same. But even when you do consider “OK” a good enough response, do consider at least for a moment the potential reaction from the person who sent the text in the first place.
Okay and the abbreviations OK and O.K. are informal and should be replaced by synonyms such as acceptable, all right, correct, approval, authorize or recommend in formal writing. Ian says he'll be okay (all right) once his cold clears up.
Dry texting is what happens when someone gives you short, non-engaging replies in a texting conversation. It can also be super repetitive and just plain boring, says Claudia Cox, a relationship coach and founder of Text Weapon.
Time-sensitive messages should be answered as soon as possible, while you have more time for nonurgent ones. But not that long. Gottsman, speaking "from a polite factor" believes you should respond within a day.
Give it a few days (or even a week).
Waiting 2–3 days or up to a week before reaching out gives him a chance to text you first once he realizes what he's missing. If you've waited more than a week and still haven't heard back from him, it might be time to move on.
