This always makes me think. Cockroaches don’t bite, are not venomous, basically can’t do us any harm. I’m not afraid of wild dogs, spiders, tarantulas, scorpions, snakes, wolves, hyenas, wild hogs, bears (encountered them all) but I might actually scream if I get surprised by a cockroach.
I think this collective fear of cockroaches that we have cannot be without reason and must have an evolutionary reason.
If I was at a friend’s place and a dozen wild hogs scurried away when I turned on the bathroom light, I would be startled.
And confused, I fear.
