First-world dilemma, I know, but I'm genuinely unsure. Context is that I run a small interest-based social club and we've had a few new joiners lately. I don't want them to feel 'outside' of things, so to speak, and I have some bad memories of joining social clubs myself in the past and just being left out on the fringes, which is possibly making me overthink this.
Basically I always introduce people (on both sides), but in some cases it seems to be meeting with a bit of puzzlement. I'm wondering if (a) the times have changed (I'm in my mid-50s) and no one does this any more, and/or (b) as they're grown adults I should be leaving it to them to introduce themselves. But I would then worry that the new people didn't feel welcome! (Again, my own past experiences might be feeding into this.)
YABU = they're adults, let them introduce themselves to each other
YANBU = introducing new people to each other is a nice thing to do
