Oh you mean like just saying "goodbye." I don't even think about it usually.
But if you mean like endings with people I love, I'm more like Avril Lavigne in that Goodbye video with mascara running down her face, crawling around on the floor, taking off her wig and drinking wine alone in a motel room like "PLEASE DONT LEAVE ME."
Actually when my ESFJ ex and I broke up, he was like "I have this feeling I'm never going to see you again" as I got in the cab to go to the airport to WV, and I thought he was being ridiculous, my mind didn't even accept that, I was like "sure, yeah right."
But then yeah we never saw each other in person again.
So I think maybe I don't take goodbyes seriously enough?
Perhaps it has to do with being counterphobic, because it takes me FOR FUCKING EVER to get over ANYONE.
