Stubbed toe
"Foot. A device for finding furniture in the dark."
Without light, you cannot see. Therefore, you must rely on feel. Sometimes, this occurs through pain, such as stubbing your toe on the chair that the cat uses as a booster to get on the counter. Yes, you read that right. My cat, belonging to a species that is renowned for jumping capability, needs a booster chair. I very rarely stub my toe on that chair in the dark. It happens in broad daylight far more often. Perhaps in the dark, I'm just more careful. Or maybe I'm afraid that hitting the chair in the middle of the night will wake up my parents. I hate waking up my parents. I once slept in the hallway of a hotel, because I thought I was locked out of our room and didn't want to knock. Turns out you just had to push the door instead of pull. I guess that cat and I are both defying the odds. I don't stub my toes in the dark, and she's a terrible jumper.
