Worms...which is so weird, because I don't mind snakes and bugs that much, but worms and caterpillars terrify me. If its going to rain, I make sure that I'm parked in the garage so I can go from the house to work and never have to be outside where they might come out and be lying on the pavement. And my poor boyfriend has to change his whole schedule around when its rainy because I'm absolutely not walking the dog in case I see one.
