What's your newest one? Forget something important? Behave cluelessly in an obvious situation?
Mine: I got out of my car at the mall and started walking away until my SIL informed me that not only had I left my keys inside the car, but the car was ON! Ughhh, I'm glad I'm trying to give area thieves a leg up! Thank God my SIL noticed!
Oh and I went to the store today for two items: fruit and waffles. I spent $50 and forgot the waffles, which I didn't notice until I was home.
