FOUND: A memory that isn't mine. Found it in my coat pocket. (Cawlish)

Pulled a memory out of my coat pocket this morning that isn't mine. Somebody's birthday party: a backyard, a cake with too many candles, a woman laughing who I've never met in my life. Feels like age 8, maybe 9. Not mine. I grew up in Cawlish, this yard had trees I don't recognize, and my family wasn't really a birthday cake family. It's a nice one though. Warm. If it's yours, I don't mind keeping it safe, but wanted to post in case you've been looking. I wore this coat to the swap meet on Fossway last weekend so it probably got mixed in there.
