Do you ever just not respond to a question because the only replies

Just say it

All the time, same as "you didn't need to private message to say thanks" or a ton of random.other thoughts I have. Easier for me to just ignore. Some don't understand everything isn't an invitation to them personally.

Lol I usually reply to anything where I can attempt to add some humor even if it's stupid shit. Unless it's some goofy political post then I avoid it like a plague.

It depends what kind of mood I'm in, sometimes I give a rude answer, other times I hit the X

if those responses are appropriate, those are the ones that I give..

If that's all I can think of, then I'll just use an emoji...

Or "what?" Or "Oh" or "Thats sad"

Depends on the question and questionnaire.
Some questions don't make sense and get the comments you mentioned above.

It is to easy. I mask it with sacrasm

No.
