A friend of mine has a transwoman friend who calls himself Elaine. Given that Elaine is ex-military, there's no doubt what diagnosis we're dealing with there. He has ingratiated himself into a female friendship group, with all the little handmaidens (including my friend) showing their woke credentials by validating him. When my friend and I went on holiday together for 10 weeks, "Elaine" volunteered to sleep over in my friend's house as a security measure. I have found out so much about AGPs lately that I strongly suspect this was prompted by a fetishistic desire to occupy what is very much a single woman's living space. (My friend turned him down with thanks, as the insurance policy didn't require it. But wasn't that such a sweet gesture, she tells me. I bite my tongue and change the subject.)
The narcissistic ones are the obvious ones, the tip of the iceberg. They're all at it.
