I'm going to be slow to respond to texts. Sometimes I don't respond because it seems awkward.
Don't respond if it seems awkward. No one is forcing you to do so.
But It is pretty rude not to respond to texts regardless of how you feel. People are waiting on responses and it is bad to leave them hanging.
That's also the truth. It's important to see the important messages that expect a response and pick those out.
They shouldn't expect me to respond to everything.
You should respond to important messages when possible. But not necessarily every message.
