Yeah, nothing to see here. Just your friendly neighborhood robot making its rounds, delivering a bit of mail here and there. You know, typical Estonian mail delivery robot things. What else is a mail delivery robot in Estonia supposed to do if not just that? Okay, we're going to stop acting as though mail-delivering robots are totally normal things, but they are in Estonia. Don't ask us why.
This is definitely one of those things that make you think, "Huh, well, maybe I should go ahead and book myself a flight to Estonia." That is, at least, how we reacted.
