My terrible super power is being incredibly oblivious. I've had more than my fair share of occasions of hanging out with friends etc and someone says "OMG did you see that thing just now?"

Nope. I did not. I was listening to our conversation, thinking my own thoughts, and/or starting at the ground or into space.

This is partly innate, because I am very internally focused on the things happening in my head, and partly a learned avoidance response to: 1) instability in my family during childhood, and 2) street harassment and creepy dudes. If I didn't notice it, it can't hurt me, right? (Obviously wrong, but this part of my brain isn't logical.)
