When I grow up, I'm going to have my first kid read the Harry Potter series and convince him that he's a Wizard, too, and he'll receive his Hogwarts letter when he turns eleven. Sure enough, on his eleventh birthday he'll check the mail to find the letter ( written by me, obviously) and in the fall, I'll take him to King's Cross, point him towards platforms nine and ten, and not say a word as he collides into the pillar.
