Clumsiness.
I'm expecting a delivery and since I live on the fifth floor, I need to get notifications on my phone, which has unreliable coverage and sometimes goes to voice mail instead of ringing as a call.
My phone just pinged, so I leapt up in case it was the delivery guys leaving a message, not wanting to risk them leaving before I got downstairs.
Of course, my laptop shot off my lap, straight down onto my toe, which now hurts like hell, elevated or otherwise, won't bend and is bright red.
I'm used to my elbows and shins being bruised long after I've forgotten what I bumped, but now I have to worry about toes?
Naturally it was a cold call, and since I answered, they now have a phone number belonging to a live person to harass and with a number to sell on. Double peeve.
