I left my computer on last night to download Critical Mass while I slept, but since the screensaver is kinda bright I partially-closed it so it wouldn't brighten up the whole room when I turned my lamp off. Unfortunately, my cat Piper likes sitting on the lappy, and at some point during the night she stepped down on the back of the screen and closed the computer. This of course put it in sleep mode and disengaged the wireless connection, so it didn't finish downloading last night.
Happily, it is now at 91.5%, so it's really not awful. I just felt like sharing.
