I am an introvert until the moment I see someone is looking uncertain, uncomfortable or like they need assistance, then it is like a switch flips and I am mama bear making sure they are OK!

I was on the train home one night (I live in NYC) and a man’s grocery bag broke. His groceries were rolling around the train car and everyone wordlessly picked them up and returned them to him, and those of us with plastic bags we were able to part with offered up our bags to repack his groceries. There was no discussion. We all just handled it and went back to minding our own business. It was beautiful.
