I've found this to be a common conversational style among those w/ADHD-like behavior, esp those on the spectrum & prone to getting very excited about things; personally, I find this type of spastic free association rather tiresome & get annoyed if they don't try to stay focused
this naturally leads to unbridgable conflicts in conversational style, w/ one or more of the parties getting increasingly annoyed, unless someone compromises on their preferences; tbh I don't really find this spastic preference to be valid, as it leads to unproductive discussions
