I find myself looking at profiles on OLD and thinking "oh he might be the one there was a thread about earlier" or "hmm, I bet he's the one that that poor woman on mn had trouble with" or "ooh perhaps this is the man whose partner posted on mn about finding him on dating sites".
It's hard enough as it is without me now factoring in extra (and probably completely irrelevant) obstacles! But all the awful men on here must end up somewhere - and knowing my luck, they'll all be on the OLD sites I try!
