Well doc, you're operating on the assumption that everyone here is rational. On the other hand, there are so many here who like to feign indignant and so, separating the wheat from the chaff, go back and look at your (former?) friend and read their body of work. Do they appear to be rational.....sane? If the anwer is "yes" then perhaps some other trigger set them off or.....heaven forbid.....they looked at your body of work and decided you were not their cup of tea.
It happens. No shame. You've tried to apologize so let it go. I have experienced the same thing here, so have others.
You have to remember.....this is just a flat screen presenting people to you from a website you don't even know. Some are genuine, some eccentric....and others are a mixed bag of fetishes and assorted con artists, salted with a seasoning of immature deviants. Occasionally.....jussssst occasionally, a few brilliant people arrive. They amaze a few who get it before leaving as the came.....with nary a whisper.
It really comes down to that sense of savior faire and hoping those who fascinate you come wrapped in the same paper.
Should your return be empty.....c'est la vie auld boy....eventually a gem appears out of nowhere.
Until then.
