When I was younger, my sister had a problem with flooding the toilet a lot. I was always scared that I would flood it, so I always shut the lid, washed my hands, and then flushed as I ran out of the bathroom - thinking that shutting the lid made it not flood. Even today I can't shake the habit of shutting the lid.
