I've lived with numerous relatives and roommates, and not one has ever filled an ice tray. I always find that I always fill the ice tray.
My roomies will even put empty ice trays in the freezer, and if I'm gone for days, I find they actually buy bags of ice instead of filling ice trays.
So, I'm led to believe that I missed the lesson that tells us we go to Hell if we fill up ice trays. They all knew the law about filling up ice trays, but they wouldn't tell me about that secret law, because someone has to fill the ice trays up, and the ice tray fillers go to Hell, I guess, because you go to Hell if you fill up an ice tray.
