When EtheSecond is 16 and in that "sleep all the time" stage, I'm going to play him recordings of himself from the past week's 2 AM freak outs. At full volume. 20 minutes after he falls asleep.
When EtheFirst is all grown up and taking care of my infirm self, I will tell him I want oatmeal for breakfast even though I really don't. Then, when he brings me oatmeal, I'll throw it on the floor and cry until he brings me a peanut butter and jelly sandwich. Toasted, but not crunchy. After that I'll berate him for not being able to put my oatmeal back together.
And both times, I'll laugh my ass off, then shout "look what I'm doing" and show them how good I am at sitting on non-chairs. Because they should know!
