For me, it's lizards. As a boy, I used to spend hours when on holiday trying to catch common lizards with very little success. Now I'm able to see them without the urge to catch them, but they still hold a fascination for me.
I love being on holiday in France where wall lizards are so common. It's wonderful to be enjoying a drink in a cafe or on a terrace and have lizards appear and walk under the table. I can't resist them.
