The fact that he said nothing about her for more than four years merely indicates that he’s not obsessed with her. I would also say that it indicates that he does not have PDS.
Considering the amount of nutty stuff that’s been posted here over the years by some people, I would hardly say that his opus was that much of an overreaction.
Because of course, we all opus whenever someone makes comments we haven’t discussed in 4 years. It’s a completely normal reaction.
I remember on a music forum once...some guy said he hated Roland Jupiter 8 synths. Considering I hadn’t mentioned one in 4 years, I took great offense and opused immediately.
Perfectly rational reaction.
