It turns out gamemaker and skeleton_kiss, whom we had never met before, had seen us approach a few sets and from how we carried ourselves correctly guessed that we were from the community.
Cool guys, both of them.
They hadn't opened very many sets so far, so Fenix and I talked some basic game fundamentals (which I think they already knew) and just started pushing them into sets.

Just recently I've consciously realized how I like to run an opinion opener, or a similar "spontaneous" opener. The way I was taught, I would be walking past, and "just happen to notice" and open over my shoulder with an opinion question. It feels weird though because even though it's indirect, I feel awkward because i think they're going to know that I started talking to them on purpose.
So instead, wing and I will walk, and we'll stop near a set I want to open. We'll talk for a couple minutes, about whatever, and then I'll open over the shoulder with something. It feels so much more natural.
Thinking back, I've done this a lot, but I didn't really notice the pattern to what I was doing.
Those of you who have been out with me, especially recently, can probably think of examples where I've done this. Now that I think of it, I do it this way most of the time I think.
Skeleton_kiss and gamemaker, y'all are cool and need to hang out with us again. You've got potential. All you need is to be out in field and opening sets.
