That is so odd, that's how I am with peas. Growing up my brother LOVED peas so my mom would make them for him and I would run out of the house complaining about the smell. Which everyone would say I was being over dramatic because peas don't smell. But they do and it's rancid to me. I could smell her cooking them when I was clear across the house.
And I don't blame you about the smell of cheese. It is strong and It is pungent, it also lingers. The deli I go to by my house makes all their cheese in house, the smell is STRONG, to say the least. I can't even be in there longer than 20 minutes, and I usually end up smelling of cheese until I get home and shower.
I know it is weird but I love spiders. I can't kill them, I usually just scoot them outside. Unless they are bigger than a grape, then I am sorry and will hold a small funeral after I murder it.
