My fear is rational and irrational. It is rational because some snakes are poisonous but on the other hand, even ones that are not poisonous scare the shit out of me, that's irrational. It's a small phobia... For example, some spiders are poisonous and I wouldn't take the poisonous one in my hands but there would be no problem with a harmless spider. Snake on the other hand, is out of question regardless of poisonous or not.
