Goddamnit, I knew I was forgetting something yesterday! I'm so ashamed of myself for not remembering my boy Usopp's birthday. Fuck.
Y'know that makes me think: What are birthday bashes like on the Thousand Sunny? You think they have to keep an extremely close eye on Luffy so he doesn't eat the whole cake before the birthday boy/girl? Or that they throw surprise birthday parties despite living in such closed quarters but it works out better any time they get to port? Or in the case of Usopp, they forget it's his birthday because he's a habitual liar, for one thing, and also 'cause he's consistently pulling pranks for shits and giggles and they forget 'til the last minute to celebrate? Or how about when it comes to Brook? Does he celebrate his birthday, or his death ("death"?) day in good spirits?
The endless possibilities, man.
