Yeah just be the bigger person.
I have some idiots like that at work anyway.
No matter how much of an ass they are I still interact with them. After all you still have to get the job done.

Managers/ supervisors, workers etc.... all work together.
Its better to get other opinions then to do as you say and end up fuxin up.
