Someone asked me to post this anonymously:
I received a New Years card from one of these phone "sex therapy" services that I called a few times before my GYE days. The return address is very discreet but, based on the postmark, I realized who it was from (I called last year and requested to be removed from their list, but they obviously didn't listen).
I didn't open the card. Rather, after removing the address label, I got rid of it. As much as I'd like to call them up, maybe to tell them that the person no longer lives at this address, I think that even making such a call would be too much of a trigger.
Anyway, I needed to get this situation off my chest - thank you all for listening!
