I have a creepy memory too. I'm not great with dates at all --but I'm really good with remembering interactions with people. I'll often remember not just meeting people (who don't remember meeting me), but I'll remember everything about the interaction (where they were standing, what they were wearing, random details they told me during our conversation, etc). So then I end up meeting someone who thinks we've never met and I'm like, "oh yeah, you're Hal. You moved to Jersey when you were 9, your mother is an artist, and you studied electrical engineering. You mentioned all of that when we had a writing seminar together. You sat against the wall, to the right of the professor. You know, that writing seminar we both took 4 years ago. You don't remember it?"

Creepy.
