I asked my 6 Y/O nephew what kindness meant to him and he replied walking an old lady to her car. So I asked him has he done this before and he said I walk grandma to her car all the time. I laughed and told him to remember to never refer to grandma as an old lady in front of her and that it wouldn't be in his favor : )
I thought this was a fun activity to get insight of a child's mind. This activity really put me in a positive mood.
