Squishing bugs. I just can't do it. I'd rather ignore ants and spiders, etc., than contemplate squashing them.
The smell of roast duck. I really can't stomach it. It's a curse, because Egyptians (one to whom I'm married) seem to think 'God got it right with ducks' (a direct quote). Somehow, I can't imagine God meant to create an animal that smells like dirty socks when it's cooking...
Gin. There's a story behind that one, but I don't think I'll share it right now!
Bad reviews. Enough said.
Leftovers. Bllleeerrrrgggh. Cold, minging bits of cooked food turn my tummy.
Actually, that was surprisingly hard. Maybe I'm less squeamish than I thought!
What makes you queasy?
