19. Elementary School
My family was at the county fair for the day. As we were sitting down on a porch I leaned against a wood post and caught my back against a nail, hard enough to break the skin. I don't remember much about it except crying and my father taking me inside the shop or somewhere for antiseptic, probably hydrogen peroxide. And then again, a few weeks later, sitting on the couch in our living room when it was time to take the bandage off, me insisting that he pull it off as slowly as possible and him explaining that it would be better to rip it off all at once.
That's invariably what I think of whenever someone says "rip it off like a Band-Aid."
