Someone's Grandma

I got yelled at by someone's grandma this morning - not sure why, it was in Polish.

I was riding the tram on the way to the office, just looking out the window. The tram stopped and the door opened and I found myself looking down at someone's grandma. She had a crutch in one arm and a shopping cart in the other and she looked at me and I looked at her and she just started yelling at me.

Ultimately, I stepped down and grabbed her cart and puled it into the tram and then turned to her and guided her buy the elbow up into a seat. She pulled her cart next to her and looked away. I have no idea if this was the right thing to do or even if she merely followed the cart into the tram so that I didn't steal her groceries. I turned around a stop or two later to see if she would smile at me or even thank me (though I am not sure I would recognize that) and discovered she was gone.
