Decades of pointless fights and stupid jokes while the problem was easily solvable from day one.

Keeps the cats out

Yeah ironically growing up this was the argument. I closed the toilet lid and my sister was outraged. She eventually went to my mother and asked her to talk to me about the toilet. So my mom brought us together and said "lengau, you need to stop leaving the toilet seat up." I looked confused and my sister said "no, he keeps closing the lid!"

My mother burst into laughter and told my sister that she should do so as well.
