Browsing through the ads recently I recognised something - not a face, nor a name, but the background. I am 99% sure the photo in the ad was taken in the front room of a business colleague in another city. I've been in that room often and get on well with him and his wife who is lovely. The location was right, the ages were right, it must have been the same room. I don't want to embarrass them, but on the other hand I'd love to get it on with them. But what if I'm wrong and it wasn't them, or worse, if it was one of them and someone else and the other one doesn't know? I could reply to the ad, but that means sending a photo, and the risk then is that they'll know about me but decide not to meet. I'd never know if my colleague was in on my secret or not!
Any advice please?
