Tuesday evening, I told Scott the story. I said I wasn't sure how to render lobster arms as an emoticon -- 2 lowercase f's? Scott commented that mirror-f's aren't on standard keyboards and suggested an f and an r. I said I'd totally forgotten about the mirroring requirement, and then pointed out that it could be a sideways facing lobster. He then suggested a capital F since lobsters have one claw bigger than the other. ♥
I don't actually know what a lobster arms emoticon would indicate. My first impulse is to want it to indicate amusement, given the aforementioned "dissolved into giggles," but I feel like "crankiness" or somesuch would make more sense given it's supposed to evoke lobsters.
Attempting to type them out now, I find that they look so much like words that I have difficulty parsing them as emoticons :/
