You often come home covered in paint, glitter and gloop.
You end up getting colds all the times because illnesses get passed around so quickly.
You constantly have all the songs from work stuck in your head.
You get annoyed when people assume your job must be really easy.
« You just hang out with kids all day » – someone who does not understand your job, at all.
You learn to not be squeamish about poo.
Once you've had to stop a kid from trying to eat their own poo, very little fazes you.
