Why didn't you get Kall to clean it up in the first place :P
and What was he doing with spray and wipe beside the computer...
Also I know what you are saying about men! The other day I came home and before I had gotten anywhere near the fridge asked number 1 flatmate if he had eaten any left over macaroni cheese yet, the response was really grumpy and he started going on as if I had accused him of eating it all.
When all I really wanted to do was to offer to heat him up some too while I was doing mine if he hadn't already eaten. Geese after that I told him to sort it out himself. Which he duly did (however I do note he left it for like a couple of hours until he felt it safe to come downstairs again! hahaha)
