We spot a copy of the Guardian, with a strapline for a feature inside "Is a folding bike the answer?"
Jonny: Do you want to read that?
Me: Nah, I'll pass. I expect the answer is yes.
Jonny: You never know, depends on the question.
Me: Yeah, I guess. If the question is "How can I complete an efficient multi-modal commute without a car" then 'A folding bike' probably is the answer. But if it's "What was the state of the universe in the seconds after the Big Bang", then it probably isn't.
Jonny: Haven't you heard, that's exactly the latest theory. All the power in the universe created in an instant, in the form of an ever expanding folding bike.
Me: Nah. It wouldn't be a folding bike. It'd be a Dawes Galaxy...
It's conversations like that that make the job fun.
