We were invited to a summer party today at the home of one of my colleagues. We had a lovely time. It was almost perfect weather - warm and sunny but not too hot. E5N1 ran around and got wet in a water fight and enjoyed his first NERF battle, but also enjoyed hanging out in the tree-house with some of the quieter kids. He and Exile #4 helped to destroy the piñata and the rest of us just hung out - ate and drank and had some nice conversations.
(It looks a bit like we were alone - there were lots of other people there, but I decided not to post photos of other kids.)
