Should women be allowed to hang out with their friends and host a girls night out at home?

Men are always hanging out with each other without us, shouldn't we ladies be able to have a little fun too. What do you think about that? I had in mind to host a girls night out party with Ho Hum Girl. I figured that I would gather all my close friends hang out and shop a couple of things. I checked out their website, hohumgirl.com and their prices and inventory are great as opposed to other companies. What do you think about these type of parties in general?

Allowed? I'll do what I want when I want. But then I'm always invited to the guys nights. Guys are more fun anyway. I'd rather watch UFC than talk about make up and hair.
