What animal (or insect, etc) are you most afraid of? Was there a specific incident that led to your fear, or is it just a general thing?
I hate wasps (UK). They are evil and will sting as a weapon whereas honey bees (UK) can only sting once before doing so kills them and so use it as a last resort. Wasps will sting because they are annoyed, pissed off, scared or just because they feel like it. Evil buggers.
