The last two times I hired a babysitter to watch my kids had been awful experiences.
The first sitter I hired after I had seen her ad posted on the wall at a strip club. She mostly did escort work, bachelor parties, and bar mitzvahs but was open to babysitting. When I talked to her it was clear she had a serious problem with drug addiction and would do anything for cash. I had not planned on hiring her but I had gotten stuck attending this holiday party at my wife's office at the last minute. It is impossible to find a sitter at the last minute during the holiday season. We got a little drunk and had to spend the night at a hotel. The next morning when we got home, I found all our possessions gone, stolen in the night by the babysitter. Worse, our kids had spent the night locked in the bathroom.
With the second babysitter, a portal to another dimension had opened in the children's closet, pulling the babysitter and one of the children into a hellish other world. Even worse, the portal somehow caused rotting undead corpses to erupt out from the ground throughout the neighborhood that went on a murderous feeding frenzy. Then the house somehow folded inside out before getting pulled entirely into another reality. None of which had been covered by my homeowners insurance. I swore it would be the last time I would allow someone with a name like Azathoth the hellbringer to babysit my kids. In retrospect, the cultist forehead tattoo should have been a red flag.
We had all these NASA scientists going in and out of the hell portal for weeks running tests. They left me a business card in case I ever needed a babysitter again.
