Play date - why? what?

We're about to have our first play-date with a classmate from school. You ask how we've managed to avoid this - I really don't know. But, it feels so completely different than when my girlfriends visit. I don't even know the parent involved (Hubby set it up) and I feel like it's a big test. What will we talk about? Will we even have anything in common? How are we supposed to entertain the parent while the kids play? Do we drink? Do we watch tv? What!?!?!?!?!?!? I'll update you when it's all said and done.

Update - It wasn't as bad as I thought. We talked about the kids and what was going on with each in terms of milestones etc. We (more the other mom) basically followed the kids around the entire time. We did drink however - we both had a glass of wine. But, I really thought a play date would be good in terms of getting daughter out of our hair for a little while because she and her friend would play with each other. Instead it was like having a play date for us because both hubby and I were forced to entertain playdate's mom the entire time. She was pleasant and conversation was easy - but, really, I just hadn't expected that. I guess it's one thing if it's your friend but when its the first time meeting someone and you're forced to find stuff to talk about for 2 - 3 hours...that's another story.
