What's that yellow thing?

The sun greeted us as we stepped off the sleeper at Euston and headed to St Pancras for the train home. You could argue that we should've cycled home from Euston, but we couldn't be bothered. Instead, we sat in the sun until the train came, then sat in the sun in the back garden apologizing to the menagerie for leaving them for a week. I think we've been forgiven.
