I'm not in an anime club, but I'm sure there is one in my godawful school.

[Jub3r7]

[Ruto]

That's me every night except Saturday night.

It's motion sensored so when I wake up in the middle of the night to use the bathroom, it turns on so I don't have to trip and fall and die.
Turns off after 90 seconds.

The person below me one one of the people that already knew that.
