We are mid 50s and matched with a mid 20s couple, my brain wont let it land as normal

so here we are. me 54, dh 56, been in the LS about 7 yrs, mostly play with ppl in the 40-60 range bc thats just kinda where our orbit sits. last week we got a really sweet msg on SDC from a couple, she's 26 he's 28, married 2 yrs, been in the lifestyle since they were both 24. they referenced our bio properly, sent a normal pic, totally not creepy. and now we have drinks on the calendar for next thursday and I cant stop running it through my head like is this... ok? like rationally I know its fine. they're both very much adults, theyve actively chosen us, theyve been doing this longer than some couples in their 40s tbh. and yet every time I picture us walking into the wine bar I get this little flinch of "what are we doing". I keep thinking about how when we got married she wasnt born yet which is the kind of thought that should NOT enter your head before a meet, and yet here we are. dh is being very chill about it which is fine but also a little annoying lol, like babe at least pretend to wobble with me. when I asked him directly he said "they messaged us, they want to meet us, we either trust that or we dont". which is correct and infuriating in equal measure. oh and the other thing — I keep wondering if when we actually meet I'm going to suddenly clock how young they are in person in a way the photos didnt convey and just... freeze. or worse, get all weird and motherly. anyone been in the older half of one of these? does it land normal once you're in the room or does the gap stay loud the whole night.
