I think I would have a previous commitment that night. I like my dcc just fine, and their families too, but when it's home time, I can't wait to get my quiet house back. I have no desire to socialize with them. They are clients, not friends. I do have two who work together and have become friends, with playdates on the weekend with each other, and I think that's lovely. But I don't really want to encourage them all to become a "group." I can see trouble there.
