So, I walked into Allyson's school today and was stopped by one of her teachers who asked me if we had had a house fire. We hadn't so I said no. She told me that Allyson was telling everybody that our house had burned down and we'd been living in a hotel for seven years. It was the 'seven years' that tipped off the teacher that Allyson might have been making it up.
When I went to the playground to get Allyson, I asked her if she'd been making up stories and another teacher looked at me very relieved. She had been worried about our family having to go through so much. I guess she didn't hear that we'd been living in a hotel for seven years.
Allyson told me she made up the story because it had happened to one of her friends from school. I know this wasn't true because I had just driven by that friend's house on the way to pick her up.
I guess what I've learned from this is that Allyson is a pretty convincing liar.
