I shouldn't buy a bunny because:
1) I don't know where I'm living next year
2) This non-existant (yet) place may not allow animals
3) It probably won't have a garden
4) I don't know if Rob likes bunnies
5) It'll need to be neutered (& fed)*. This costs money
6) The cute one in the pet shop was far too docile. Psychotic bunnies make far more interesting pets
7) I want a dog. It's a bad idea to have both

So why am I re-reading my book on how to look after rabbits?

* The bunny. Not Rob. Well, maybe Rob.
