My mother convert to witness when I was five years old. Until then she was Baptist. However, she learned goodness from her parents, and passed it on to her children. She will go out of her way to help anyone and does not hesistate even if giving a witness is not her goal.
The sad thing is that growing up I thought that really only witnesses taught this. But then I realized that you dont have to be of a certain religion to be good to others. It took many years to realize that.
