One of my friends asked me what I was studying, and I didn't manage to get beyond, "At this point, I'm analysing OTP" that she immediately interrupted me and started gushing enthusiastically, "Ohhhh they're allowing you to talk about your fictional One True Pairing? I thought you weren't into shipping!! This is super cool! So tell me, which one is your favorite couple, and for which series, and why?"
And I was just staring at her numbly before managing to explain, "Uh, no, by OTP I meant 'One Time Pad', the concept in cryptography that encrypts a message by using a code key only once." My friend, extremely disappointed, just shook her head and replied, "The stuff you study is so weird."
