I can be the extrovert when at the grocery store to help someone etc, but generally introvert.
The people in my apt building, I mostly avoid. A few are kinda scary. If you didn't vote for their person (Hillary), or dont want to gossip, it can get ugly. Had one woman come up and yell at me for voting for the person she hates. Yet she was guessing. I don't tell her that stuff she just figured because I don't like Hillary she had me all figured out. This woman is almost 80. Good grief. Use the little energy you have at that age, and be kind to someone.
One person here was spreading a made up thing here about me dating a man here in the building, and people found it funny. She is always trying to re-connect, but I won't do it. She looks so baffled. I actually caught her spreading the story, and confronted her angrily. Only one of the people she was telling people this apologized. That is pathetic. Only one. They knew I was angry and hurt by it.
So, it is situational.
With family and close friends I jabber away quite comfortably. Just a different world these days.
