#39: Expensive Envelopes
This is a classic case of a kid getting a piece of information without context and completely misunderstanding it. I totally get why a parent would be annoyed at a kid drawing on an envelope—they are a very particular type of paper product, and you probably have a finite amount in the house—but they are definitely cheap.

For me, the weird thing that got stuck in my head for the rest of my life was that if you eat too fast, you’ll get fat. Not if you eat too much; no, I thought the sole decider on whether or not you gained weight is if you ate slowly. As you might guess, I ate slowly all the time, which isn’t necessarily bad.
