Your probably closer with your first assessment but only a guess about OCD but maybe trauma related OCD when you can’t get something out of your head that causes anxiety. As you can see it can cause others anxiety with their obsession so therapy for all affected No Frosty shows for awhile. Pass the posts because your going to get anxiety then fed up which will cause anger. Frosty should have no twin towers exposure but I’m guessing that would be a challenge.
Silverngold, well said.
