Mine rarely ever do! I could push them into each other so they're staring right at one another and they'll just walk away... I wish they would talk to each other more, it's cute! :c
I wish my villagers would interact more often. I've only be able to hear in on a conversation several times. It's especially frustrating when I see two villagers interact, run up to them and just miss it.
Oh, my villagers rarely talk to each other. They usually fool me when I walk past and notice two villagers standing together and staring at eachother, then they will just walk away @~@ Kinda like, "Aw gosh, here she comes that annoying little -.. OH HEY MAYOR, you look chipper as always!" :I
It happens every now and then, but not too often considering how much they walk past each other. Most of the time I just see them with their faces awkwardly pressed together, not talking at all.
My villagers almost never interact, and when they do, I always miss it by seconds.
My villagers are always spreading shirts and catchphrases and walking around singing/moping/throwing tantrums so they obviously do interact, but ... I never get the chance to listen in!
However, just in the last couple of days I've seen and been a part of at least three or four! It was really awesome to finally see some new dialogue and conversations.
