Actual thing that happened to me yesterday:
Sat down to write an email to Yaakov's teacher. Mid-composition, remembered that I don't actually need to write this email (because I was going to see her later in the day and could just ask her in person). Got up. Ate Snickers. Returned to computer. Thought, "Hmmm. Why did I never write that email?" Halfway through email, remembered:
1. I am going to see her later in the day and can just ask her in person.
2. I already had this conversation with myself.
Also: I've been turning off the oven mid-cookies. The timer dings, I take out a batch, turn off the oven, and slide in a new batch. When I return 10 minutes later, I am surprised that the cookies are taking soooo long to bake. I concoct a bizarre theory regarding oven temps and cookie batter. I turn the timer on for another few minutes. Only when the timer dings again, and the oven is practically cold to the touch, do I realize what I've done.
And this happened to me twice. Within two weeks. The second time it happened, you could reasonably have expected that when I encountered the strangely uncooked cookies, I would have remembered that a similar phenomenon happened recently, and that phenomenon was due to my twitbrain deciding it was time to turn off the oven. However, if you expected that, then I am disappointed in you. Don't you know me better than that already??
So the mind is not what it used to be, is what I'm saying.
At least I remember both my kids' names.
