It takes a lot of strength to work with kids! No, not just because of all the "responsibilities" and "making sure they're still alive" boring stuff, but also because it takes a lot of inner strength to be able to stop yourself from swearing all the time.
I might have a mouth like a sailor, but you can bet your... butt that when kids are around, I'm squeaky clean (see! I did it just now)!
But everyone makes mistakes, right? Even Tim Allen!
