The babysitter

"Mommie!" The voice of a young girl screamed and a pretty three year old came running out of the bedroom and through her arms around Dennis' legs and hugged them tightly. "Oh Mommie I missed you so much."
"Oh there you are Missy!" A lady in her fifties said. "I know you had to stay the night with that man of yours, but I told you I had to leave by ten o'clock and now it's almost half passed. Well, the next time you need a babysitter for Maggie, you'll just have to find someone else." The lady said and stormed out the front door.
"You want to play Dolly's Mommie?" Maggie said looking up at her mother.
"Uh " Dennis said suddenly terrified of the little girl, he quickly turned to find the lady who had just left, but once he had reached the door, all he could do was watch her drive away in her car.
"Oh my god what have I done?" Dennis thought suddenly realizing that he had left this girls mother passed out, in the body of a man, in a hotel room. A pang of guilt suddenly hit him as he realized that he was going to leave Missy trapped in a duplicate of Riley's body and in doing so, he would have deprived this girl of her mother.
"Mommie, can we go to McDonald's?" Maggie said pulling at the skirt Dennis wore.
"Oh my God!" Dennis thought. "Until I can switch Missy back to normal, I am going to be Maggie's mother."
