Help by teenager

I was coming home on September 6, trying to juggle a trolley and my walker, and all of sudden to my surprise there was a young lass asking me if I needed help (which I did).
I did not know this young lass, had not ever seen her before. She helped me home and took the trolley back to the supermarket. So it goes show there are some very helpful young adults out there.
