My superpower is to keep in mind the most irrelevant parts of information
(Like if I've been talking to someone about random stuff a month ago, then they remind me about the conversation, and I go: "Yes, of course. You told me about that, you had a blue T-shirt and jeans when you told me that, and I think your socks were white with tiny red stars on them, wasn't that when you told me?..")
Fortunately, most people that knows me quite well has gotten used to me spitting out those out-of-nowhere memories that has nothing to do with nothing..
Another example of that superpower of mine is when I go to the groccery store, coming home with one item, just to find out my list had 20 things on it I was supposed to buy. And most of the times that single item I come home with is the one most people tend to forget (I come home with the salt, when the rest of the thing on my list was things I really should have remembered, like FOOD, soda, tea, candy, milk, see what I'm trying to say?)
