He handed Sasha back to me on the train back from London tonight as the infant was zapping off through the carriage. Then he got off at Whittlesford,and offered to help me carry the pushchair over the bridge -- I'd already picked it up and started, so I said I was fine and explained how it's sometimes harder with two people (the baby tends to get tipped out, which is really A Bad Thing). Then I set off for Sawston and about five minutes later he passed me in his car and pulled in to see if I wanted a lift. He said something like "I feel so sorry for you!" so I had to explain that my partner had offered me a lift but I'd turned him down, because I wanted to walk. It was a beautiful night, with lots of stars visible, and Sasha needed to wind down after a busy day in London anyway. But it did seem a little sad that someone couldn't quite believe that I'd want to walk a couple of miles on a nice night. And, conversely, very cheering that people are so helpful and concerned. Having a baby definitely lets you see some of the best of human nature.
