It's funny that you say this. As I read this, I am picturing our last night of league (just Wed), when all my teammates (sans Ashley) were talking about the names. We were all laughing and cracking up and having a great, fun, laughable time discussing them! You should have seen us! I think if you met us, you would see we are just a fun group of woman.
And to answer your question, and this may shock you, two of us are in our 50s, one is in our 40s, one is in our 30s and the 20-something year old wasn't even there. So, if you are imagining a young group of "girls" being silly, we are actually fun-loving older woman who love to laugh!!
I think it's great. I see it as just having fun. What else are games for?
