What did I do wrong??

So Rachel decided to pull an "evil Rachel" routine in front of a classmate and her mother. Rachel asked me to invite Morgan over for a visit so I obliged. She was excellent on Saturday and in a great mood in the morning. Why wouldn't I everything seemed fine. When Morgan got here her little sister wanted to stay and play with Ethan (Ethan and Olivia were in the same daycare so they know each other)so they all decided to play while their Dad left to go get Groceries. Cathy, Morgan's mom, and I talked while the kids played. They were getting along great until all of a sudden Morgan comes down to tell me Rachel won't let her in her room. I went upstairs and Rachel told me she wanted Morgan to go home. Being that they didn't have a vehicle that was not an option. I spoke to Rachel about being polite and how would she feel if someone did that to her. She started screaming and crying and wouldn't share her toys. She yelled that she just wanted Morgan to go home...I was so embarrassed and humiliated! What have I done wrong?? There has been no T.V. and no candy (left overs from Halloween) as punishment but to be candid I want to take away CHRISTMAS for that academy award winning performance!!

Is there awards for the worlds worst parent?
