How did I get here?

Does anyone else feel like a huge imposter sometimes? Or, not so much an imposter as a child playing at being a grown-up? Sometimes it feels as though I've been plucked up from making mud pies and playing smurfs, and plopped down into having a child and being expected to raise him and cook and clean and recycle and keep appointments and care about the government and be responsible and I wonder how it is possible that anyone expects me to do these things well. I don't mean to complain about the number of things I have to do, I realize that everyone else has as much or more to worry about than I do. It's only that they seem so much more qualified than I, the 9 year old, am.
