I'm thinking of quitting my job because I couldn't stand to work with my friend
Why can't you work around your friend?
Because he's the dumbest person I have ever met.
You shouldn't quit a job over a friend. Try to work out your differences with him.
This is my dream and I am not gonna let a pussy derail me.
Yes, if this is your dream job then one person should not be the reason why you end it.
