Very, very funny but also deeper: men, women, commitment, love, responsibility. I wasn't quite sure how it was going to work out; it could have gone either way. The people in the story are so convincing, they're almost too real to be just characters in a book. It reads more like a slice of autobiography; you can tell the author is a comedy writer. And notice the chapter headings!
We've all done it. We've all kept little secrets from our partners. We've all avoided telling them an awkward detail or subtly skirted over something we'd rather they didn't know. We've all rented a secret room on the other side of the city where we could hide half the week to get away from all that boring, exhausting baby stuff. Oh, that last one is just me,apparently.
