(Do you remember the living room carpet?)
You fell between the loveseat and it, you sat up and didn't realize anything was wrong until you grazed your right elbow with your left hand. Sharp pain, a whole layer of skin gone--to where? When?
It stings, and you don't cry, you're just puzzled as someone goes to get a Band-Aid.
These memories, the ones where you can't remember how old you are, they're going to be gone someday. Get them down.
