I Let My Wife Date

My wife hasn't been out lately. The last time we went out, though, we ran into a friend with benefits of hers whose wife just so happened to be out of town. He introduced her to a buddy of his who was recently divorced, and next thing I know the three of them were at their own little table, and I was the odd man out! I left, ("Don't wait up!", her friend yelled when I left. She laughed.) and didn't see her till the next morning!
