Heir forgot his locker combination from when he used to be in school.  He had a dream that he forgot it while feverishly trying at the knob in time to make class in five minutes.  But he had long since graduated, and presumably locker combos from the past are irrelevant now.  They must have long since been changed, and have gone onto electronic lockers that are easily hackable.  It doesn't matter though.  He needs to remember his combo in case he needs to go back to the school and get some stuff he still left there.

Which leads us to the fact that the Heir is still having problems with his taxes.  He checked over his taxes a second, third and fourth time, and each time he did it he had to change something.  He isn't going to change them anymore.  March is coming up and he's getting late.  He should have filed both his federal and his state by now, and he's mired in his federals.  And then he found out his zip code is wrong on his W2s.  Now he has to get that correct, which could otherwise lead to an audit.  Contrary to any false reassurances people give him, he's pretty sure that the IRS will audit you for a wrong zip code on your W2s, or if you owe $8 more or $8 less than you thought, or that he still has to file by April 15 even though he expects a refund.  That and anything that he gets wrong in any capacity goes on his permanent record, and there's no way he can legally appeal for a correction or a redaction.

Why did he ever had to remember his locker combination if there ever came a time he didn't need to anymore?
