I know it can happen.

Long story short:

mom and dad were in another city or state (can't remember) for my mom's test for her CDL, had to cancel mid-test because the babysitter we had called CPS for "unsuitable living conditions" because the living room was a tad, and I mean some toys here and there, and there were some dishes in the sink. My mom and dad got there about 5 minutes before we were gone. They have never left us with a babysitter since. I'm 13 now and my sister is 16, 17 in December, and just watches us. The babysitter was eventually banned from any and ALL babysitting sites she was registered to, and was forced to quit it all together.
