I really hate confrontation.  And I don't like to be intentionally mean, so I have to vent my frustration before I reply to things.

My son has been with me probably 95% of the time for the last month or so and I get "does it every occur to you to discuss anything about __ with his dad?".   Honestly... no!  He's hardly ever been part of decision making in his life (it was usually his step mom and I because his dad was always working) and now that he's with me all the time why should I??  You want to parent from afar?  Tell me what to do and let me take the brunt of everything?  Nice.
