Pics from someone you know in real life

How would you like this to be handled? As we've found out over the last few years this lifestyle is a very small world! How would you like someone to handle the situation if you'd given them access to your pg and you know them outside of the Pie, either work, sporting club, kids school etc...? We're reasonably sure we had it happen to us a few years ago and it was radio silence from the couple, we think we'd almost prefer it that way. Would bringing it up just make things unnecessarily awkward, where you could just be blissfully unaware? We had this come up again recently, where one of us work for the same organisation as one half of a couple... much to our shame, we've ghosted them. What would everyone else do?

ps. we've all got friends that if we stumbled across we'd have a laugh, share war stories, never hook up and life would continue as normal. A lot of us on here have also made long term friends on this place, so it's not about separating the two worlds.
