Here's a quirk for you:
I am deathly afraid of and horrified by ants. But that's not the quirk. The quirky part is that I only fear and loathe ants if they are indoors.
If I see an ant outside, no problem. Crawling up my leg on the patio? Swat. Have a nice day little ant. Joining my picnic in the park? Here. Have a sandwich little ant.
Scurrying across my kitchen counter towards the goat's cheese? Oh holy mother of God. It's an ant. Hyperventilation followed by trembling followed by trepidation. Near panic attack.
Breathe. Must. Call. Husband. Breathe.
