15. “K”
(The One Word Response)
Everybody has experienced situations where they share something interesting and wait for a response, only to hear a basic “alright” or “k” from the other person.
It gives us the impression that the other person was either not paying attention or was simply waiting for us to complete speaking before moving on.

It would be much preferable to say something like, “Thanks for letting me know, chat soon” if your goal is to end the conversation with a single word.
This communicates to the other party that you valued their efforts during the contact and that you anticipate there will be more of it in the future — just not right now.
Remember that it will be ideal for you to avoid using special characters or abbreviations like R for “are” or U for “you.”
Deciphering a text message with emojis and filler words is incredibly unpleasant.
Therefore, pay attention to your grammar; it is preferable to make that modest effort than to run the danger of coming off as inattentive or lazy.
