Toilet training

While basic toilet training took only a few weeks for each child, learning a more complete etiquette is still a work in progress years later, leading to exchanges like this:

[Flush]
Mammy (to Daddy): That's amazing - she's actually flushed the toilet.
Daddy (to the 4y/o): Did you wash your hands?
4 y/o (proudly): I don't need to. My hands are smooth and soft!
