Many years ago, and both parties are no longer around (I don't think!), a client told me that he recognized a lady (from her face photos) at a Boy Scout group that he was a part of in a different part of Texas.
And I TOLD him to leave her alone. That to introduce himself, and let her know that he knows her, was a really bad idea in a long line of bad ideas.
Well what did he do? He introduced himself. This man was like 6'5" and had a position of authority in the community.
He told me that she turned completely white as a sheet, swayed slightly, mumbled a hello and walked away.
Later, she contacted him and offered him ANYTHING if he wouldn't "out" her to her son's group.
I hated this guy after that and our "friendship" suffered because of it.
Perhaps I'm being mean but I cannot imagine that absolute horror that this lady felt when he walked up to her and said what he said. Not a graceful thing to do to another person.
Knowledge is power. Enjoy your little secret and keep that smile within. I do that ALL of the time!
Just my thoughts on it.
