this just in

The kids had their first outside-the-family play-at-their house playdate yesterday.  This is the first time they have been in a non-relative's home without a parent or relative to keep tabs on them. 

I got this in a morning email: 

We were so happy to have your kids over. They were delightful and we'd love to have them again. There manners were very good and they played very well with my children.

The mom that wrote this has no idea what this means to us.  I actually cried.
