At around 11:00 PM, In bed, In the Apartment:
Me: "Hey, can I ask you a weird question?"
Me: "When you eat celery, do you get kind of a weird, prickly after-taste?"
Hilarity Ensues, non-stop laughter for about 3 minutes.
He: "Umm no? I don't think so."
Me: "Really? I think I might be allergic, do you think that's what it is? I'm going to go get a piece of celery, you take a bite, and then I'll take a bite and we can discuss."
Point of story: Our pillow talk is clearly the best.
Result: I am allergic to celery, have been for my entire life, never realized that's why I have that weird after-taste.
