Now how did I get talked into this?

Being a recently divorced guy, well not too recent, it's been just over a year now. I haven't been really active in the social scene. So, somehow (and I don't remember being drunk when I said yes), I agreed to go see Mamma Mia with my sister and her friend tonight. Yes, I must be only New Yorker left to be a Mamma Mia virgin, this is my first time, and, I'm dreading the change to that status. What was I thinking? An entire evening sitting through endless ABBA songs? I am agonizing over the fact that I am throwing away a perfectly good evening to see this?? I might need to get out of the house but, at this price? I think I should have my head examined!
