I'm going to demand that my roommate get a full time job after just getting hired on part time
Why are you being so mean?
Because my parents demanded me to do the same
It's nicer to congratulate people on their goals, not rush them to get something better. You need to be nicer to your roommate.
Screw my parents. I should be nicer to my friends.
That is a good way to approach it. You should be happy for your friends' successes.
