My mom is that way with rats and mice...real ones, pictures, even cute little toy stuffed ones.
I'm not real crazy about spiders and always go out of my way to never harm them but if I see somebody smooching their tarantula, I don't start screaming and hemorrhaging from the eyes, for cryin' out loud.
My dad has a fear of snakes that borders on insanity.
He 'addresses' that fear by killing every one he finds.
[I'm pretty sure mom isn't joking when she says she thinks gypsies took her real baby from the maternity ward and left me, instead...I'm sure not 'one of them']
