I talk to myself
What makes you decide to talk to yourself?
I'm so bored, and the people around me do not talk to me.
Being bored is sometimes inevitable. You should be careful when talking out loud to yourself around others. People may think that you are crazy and try to avoid you.
Maybe, but I'm not the guy who cares about what people think of me. I have nothing better to do.
It's still rude to talk to yourself around others though. You should engage with someone who is there to talk to you and not to yourself.
