Years ago I was at work and could not figure out why I spelled cat pee. It lasted all day. I got home and took off my very white satin shirt and went off to shower. Surprise surprise no smell. Went back to bedroom to put clothes in hamper and suddenly saw a yellow patch on the back of my shirt.... my little cat had peed on it when it was on the ironing board that morning (where'd I'd leave it after ironing)... ironing board cover had to be washed too.
I worked in a paediatricians office too..
can only imagine what some of the parents thought
