Do not hurry when visiting the toilet!

My daughter´s friend who was around 7-9 years old was going to the toilet in our home. She had been there for a while when the doorbell rang and it was her father. He was in a hurry so he shouted hurry up we have to leave. She came down quickly and they left. Later in the evening I was myself visiting the toilet and when I was going to wash my hands I touched the tap and got something soft and brown on my hand. I put my hand under my nose and it smelled poo. I checked the floor and I saw also that someone had tried clean the floor but there were two spots of brown colouring on the floor. Really disgusting! Poor girl she had such a hurry from the toilet that poo dropped on the floor she must have picked it up with her hand and that is why I now had it on my hand from the tap....
