Worst babysitting experience EVER!!!!!!!!!!!!!!

It was just a normal night of babysitting when I got attacked. It was the first time babysitting for this couple who had two daughters. One was around 10 and the other around 7. They were the DEMONS!!! I fixed then dinner and afterwards their mom said they could have one HoHo for dessert. Well the 7 year old tried to tell me that they usually got more than one. I just simply replied "well not tonight. I'm just going by your moms orders." She threw a fit. Crying and pounding her feet on the floor. I just walked away because she was too old to be acting like that. So I went to play with the older sister. We were watching a movie on Disney channel. An hour later the 7 year old came over to the couch and sat down. She finally stopped crying! She kindly asked me if we could play ping pong. I told her what her parents said, "No, because the table is put up into the attic so you would have more room to play in the garage." Once again she threw a fit. Minutes later I notice that she was gone from the famous crying spot on the hardwood floor. She came in through the garage door holding a ping pong paddle. She began to swing it back in forth while walking towards me! She hit me I don't know how many times!!!! I couldn't really stop her because I didn't want her to tell her mom that I was being mean. Just at that point her mom called to check in on things. She asked how everything was going and while I was giving her the update, the 10 year old daughter got on the other phone and said "sis is beating up Haley." Silence was on the phone and before I could defend myself the mom said we will be home right away. I was terrified that the mom would think it would be my fault for the abuse. They came home and I left. She asked if I would ever babysit for her again and I said, probably not! Needless to say... I had about 10 bruises on my legs!
