You already lost buddy.
I eventually flipped my **** on him (put it off for a good year or so cause its not my kid and I shouldn't be telling his parents how to raise their kid) and he avoids me at all costs now (or at least talks to me with more respect), but he still treats everyone else like **** with no respect.
You have more patience than me. I won't hesitate to flip on anyone that doesn't treat me with respect irl. The only exception is in the work place lol
