We had to go very slowly because of rabbits — Heloïse kept trying to go headfirst through the windscreen after them. One poor creature ran in front of us for such a long time that Simon finally stopped the car and turned the headlights off, so that it could summon up the strength of mind to dive into a ditch. While we waited he lit a cigarette, and then we leaned back looking up at the stars and talking about astronomy, and space going on for ever and ever and how very worrying that is.
