This is a wordy one, sorry[1]. And, honestly, I'm not sure that it's funny. I try to finish on a comic beat each time, and this isn't exactly a gag, but it's hardly a drama beat either. It doesn't make me laugh, but it does give me a pleasing feeling of something-I-didn't-realise-before. It's kind of comedy-in-understatement, I guess.
