I sometimes pretend to be deaf when I'm tired or not in the mood
Why is it that you do this so often?
I don't wanna talk so I pretend to be deaf, if someone asks me a question, I just ignore them.
That is a hurtful thing to do. It's rude to pretend to be deaf. There are people who cannot hear, so you should be thankful for the chance.
Nah. This has been effective for me so far.
Stop doing that, please. If you really don't want to talk, just say it to the person.
