I wonder if there is a correlation between Si and old people who like to tell excruciatingly long, boring stories. My reason being is the my grandfather (ESTJ) and my grandmother (ISTJ) would both used to do this.
I could be innocently walking downstairs to get a drink when my grandmother would spot me and call me over to sit down. This was always a bad sign. She never wanted to chat, so I had either done something wrong or... it was 'story time'. I would literally cringe. Then an hour later, when the story has about finished I had nearly TWO or THREE seconds (I'm not exaggerating!) to excuse myself and RUN. But if I missed this opportunity I would then have to sit there for another hour, nodding my head, as she continued on to tell another story that I had probably already heard before. This has got to be the most tedious and annoying thing I have ever had to sit through in my entire life.
