Once when my grandfather was watching my younger sister and I, I decided to take a shower and didn't think to tell anyone. I took my leisurely shower, and when I came out no one was in the house. I went outside to see if maybe they were out there (it was summer, so reasonable to spend the evening in the yard). It turned out, my grandfather and sister had alerted the neighbors that I had gone missing, and the entire neighborhood was out looking for me. It wasn't even that long of a shower.
