Why so yellow ?

That was damn fun. We were paiting the walls, lol . The funniest part was when my cousin ( ) slipped with the box of dyestuff, and marked 20 different objects, ( I counted them myself) including herself with little yellow spots. To think 'bout it, it wasn't really so funny, cuz we had to clean them, but...oh well. Even now they aren't clean .... but I hope it will get fixed.
