A simple act can bring much greatfulness

While waiting in the shopping line that I had been waiting in for 10min, a lady stood behind me and I turned to see that she had her hands full and several screaming, wrestless children and appeared very stressed. I looked at her and offered for her to go before me. She was so greatful that she offered to buy me a coffee. I said that there was no need but the offer was kind. I then said that she could repay me by doing something kind for another person and she smiled at the greatness of what had just happened.
