Can't be bothered to go out on this trip instead of being with my girlfriend.
Why are you hanging out with your gf instead?
I'm tired of them always making jokes about my selfies or something they think is lame.
It's mean to cancel plans with friends to hang out with your gf. Your friends are gonna be very upset with you.
I know but I don't care about them. I decided on my own which way my life will go.
But doing so this way is so rude. You should have informed your friends your feelings about their jokes sooner.
