situations like this make me over think it. SO why doesn't he want to claim the 24 year old that he is "supporting", who lives with him, who he feeds while the kid "sells" stuff? Is he a student claiming independence on Fafsa for student loans or lower tuition? Is he getting money for some type of disability from the fed or state and claiming him would "mess it up"?

I know we could say the dependent only gets him a $500 credit but hey who needs that?
