I have one useful tool in my otherwise poorly stocked parenting shed, and that is my long memory for weird things. I have a lot of vivid kidhood memories. One thing I remember most is hating being hassled by grownups.
There's a strain of human grownups characterized by their love for giving kids a hard time. They steal noses and say that tomorrow is Christmas and tell them that their awesome double play is going to be on the local news tonight and pretend to have hurt feelings over not being invited to a birthday party. When I was little, I absolutely despised this subspecies. What a bunch of jerks. As if life isn't confusing enough for kids, who land on this earth with zero information, these clowns go and tell them things that just aren't true. Then when the kid believes these stupid things, which often have anxiety or false hopes built into them, he gets laughed at by the jerk grownup, so he's insulted twice over. It hurts his feelings and makes him skeptical. Why does any adult consider this fun?
Listen up, kid hasslers: remember that you were confused, and to confusion you may return. If you tell a kid you want her to buy you a sundae, she's going to go home and nervously start counting out her pennies. Don't bug kids; they've got enough to figure out without having to worry about your dumb jokes.
