Does anyone else also hate it when somebody ignores your text and then sends you a text about something completely off topic & doesn't bother to reply to your original text
Short responses in general. If you don't feel like talking to me, don't text me back at all.
This. It at least looks like you got tangled up in something else when you don't reply. When you reply with 'k' it just sounds bratty and you generally sound uninterested.
"K" is ruder, because they saw it and acknowledged it and couldn't give a **** to answer with an actual thoughtful sentence and just wrote you off.
Where as "seen" can be an accidental opening of a text message, or they're busy, looked at the message and plan on replying in a little when they're free.
