“I think you’re lying,” Liz tells me calmly. It takes a moment for me to absorb her meaning, but when I do, my mouth actually hangs open. I am awash with shock and indignation. Did this little brat just call me a liar? How dare she disbelieve my carefully constructed falsehoods! I expend all this energy on faking happiness for her, and she simply calls me out? Children are so ungrateful.
