First of all, Bristol is a nice place to be*. There are lovely people to dance with and to play music with and talk science with and talk nonsense with. Recently I even found a lovely person who I can talk books with and fling the contents of my bookshelf at. Yes, I have just ended sentences with prepositions. Cambridge must be wearing off.
However, a wonderful weekend with old friends has reminded me of how much I love and miss Cambridge people. The undergrad timescale means that friendships seem to have just enough time to develop closeness before people scatter off to strange parts of the country. Strange parts of the country mean that travelling times are always too long, and time together always too short.
