well I'm sure his wallet doesn't have more then 100 bucks in cash at any time. why would a person need cash.
also originally the plan was to blow it all during the summer. but remember the first page, he thought he was dieing.
so technically it was a stuffty blunder that he pulled out of his few investments, now not needing to.
but since you cannot simply get them back, he's enjoying the payout for a while. and we can assume he will use some of it to reinvest in a bunch of new things.
if you really want to kiss his ass, it shouldn't be for money to buy you things. it should be stock tips on what he buys into. though i havant known him to be open about that stuff.
