My wife and her friends go to lunch together several times a year. Because I'm not a complete buffoon, I've never tagged along with them. Why would I, right? It's a girl thing. I imagine they sit around and talk about stuff that doesn't concern me. Stuff like ... well, I couldn't even begin to guess. Girl stuff, I suppose.
The point is, my wife and her friends enjoy their little luncheons and I'm glad they do. After all, I figure they need the time together, away from their husbands, so they can bond.
This is hardly breaking news, of course, but guys also like to bond. What's more, there's a need to bond, just like the ladies have.
