Babysitter.
I remember my very first time....I was 11 and I was watching 4 kids all under the age of 3.
I had to call my Dad because 3 of them were in diapers and I was starting to freak out trying to handle all of them at once.
Looking back, I can't believe the parents felt comfortable leaving all of those kids with me.
But since I only got paid 50 cents an hour for that job it was probably because they were cheap as hell and I was too naive to ask what I was going to get paid before taking the job.
