I'm upset at my roommate for buying himself a nintendo switch
why don't you like that your roommate bought a nintendo ?
I don't like video games and I think Gamejobs sucks. We should do something about that company.
It's alright if you don't like nintendo. But you cannot ask your roommate not to buy it. It's not your right to tell them what they should buy or not.
I'm well aware that it's not my job to tell them what to do but I am going to say what I want.
I hope you will decide to keep your thoughts to yourself then. Inserting your opinion here will cause unneeded conflict.
