Hmm, that would make sense. Maybe Fuuko should stop talking and instead Fuuko should send you a letter right away. [Then they're kind of doing the whole penpal thing in reverse but oh well.]

Fuuko will definitely send you something later since that's what penpals are meant to do! For now we can keep talking like this, however Fuuko has no idea what sort of things you're meant to talk about with a penpal.
