Since my recent post about a private message on facebook, a couple of other things have happened.
One was that I was informed that there was more to the story than the message on facebook indicated. Apparently his partner (who I don't think that I've ever met or even communicated with) had worked out who I am some time ago through facebook and reacted negatively. Hence, the message was not so much a response to a recent realisation but a way of letting me know that he already knew and that he wasn't being negative about it.
The other, more surprising thing, was that I got two friend requests that day from male customers who are also friends with the guy who sent the private message. Nothing specific has been said by either of them about who I am, but I think it's fairly safe to assume that what they're implying by their actions is that they know about me and they accept me.
A pessimistic interpretation would be that they are setting me up so that they can expose and embarrass me. If that was their intent, it would backfire and be a positive for me, as I am already being gradually more and more open about who I am. Being outed in an uncontrolled way would simply me a small bump on the road of life. :)
