Good Samaritans of the CostCo Parking Lot

My friend is dealing with some recent health news that wasn't fun to hear.  Stressed to a near breaking point, she made a stop at CostCo with her young kids.  As she began to load up her car, not feeling all that great physically or emotionally, a man came up and offered to take her cart.  He even waited a while as she put the remaining items into her trunk.  

When she climbed in the car she broke out in tears.   Her kids asked why she was crying.  So touched by the kindness of a stranger, she told them that you never know how the smallest thing you do for others will be such a tremendous blessing to them and change the course of their day. 

Be kind.  "Do not neglect to show hospitality to strangers, for by this some have entertained angels without knowing it." Hebrews 13:2
