maybe it is a personal ideaology thing about 'student loan money'. For example, i dont expect my parents to pay for anything of mine when i leave home, excepts for what they offer to pay for (portion of my rent) and i imagine with five kids that he would have to be pretty rich to pay for everything of theirs.
With mika's looks i can hardly imagine his dad being native american, I have a very english last name, but my ancestors moved here centuries ago.
