What this meme is all about is expanding on that, to better create a personal history that you can then use to better build personal development. To paraphrase Lindsay, "it's not intended to be a way of avoiding/handwaving actual threads but rather a way of kickstarting them and getting a better idea of where our characters stand with each other. It's a small island, and it's likely that a lot of our pups have interacted, maybe in little ways." The details can be silly or trivial (They see each other at breakfast everyday), or a shared anecdote (Remember that time when they got attacked by the angry parrot?), or the seeds of a bigger plot to be played out later.
