I have two, and one of them I have zero control over.
One is timing. I am that person who can set an hour timer (like cooking dinner or something), leave to run an errand, forget about the timer entirely, come back, walk in the front door, and 2 seconds later, the timer goes off. Or I'll put something in the microwave for three minutes, go do something else, feel like it must be about 3 minutes now, and walk back to the microwave-- either to catch it just as it goes off, or a few seconds before. This happens a lot.
The other is invisibility. I have no control over this one, and it doesn't happen often (as far as I know), but occasionally, people's eyes will slide right past me, even if I'm standing in front of them and they're actively looking for me. This has happened many times over my life, from at least high school on. It is not (or is, depending on your perspective?) helped at all by the fact that I'm also very quiet. God, I wish I could control this one.
