Trivial superpowers that come to mind are reading and typing very fast? xD Outside of school the degree of usefulness varies, but still.

A less-trivial superpower I have is establishing and maintaining boundaries with other people (in the pursuit of a mostly drama-free life, haha). Verbally, through physical space, body language, and whatever else I'm unaware of, I've been successful with most roommates, friends, profs, coworkers, people I've dated, casual acquaintances, and strangers. I think my mom and I are fairly similar in this, though she's better at it; my dad and sister are notably worse at it because they're often bad at saying no to things.
