Today I sliced three of my fingers while attempting to open a container of sour cream (this may or may not have been a sign to refrain from eating it). I only noticed a bit later when a painful tugging made me check my fingertips, where I was surprised to see blood.
I left the cuts alone, since slices often heal back together easily. This strategy worked fine until Benji came home. Then my scabs spit open from playing (tough life, I know). I got myself a couple band-aids and, while applying them, explained to my rapt audience that when we get owwies, we sometimes put band-aids on them.
