What Mommy?

So I was in my bathroom getting ready and I walked into the other room to check on Greta. She was standing there talking on her Cinderella phone. When she saw me come in, she stopped talking and just stared at me. After a few moments of silence, she says, with no expression, "what mommy?" When I didn't answer, she looked away and started talking on her phone again. It was so funny, already too important for me.
