How you look at it determines what you see

When I send out our customers monthly bills I randomly put a stamp on one or two customers return envelope. It was my way of bringing an unexpected smile to someone when they open their bill. After doing it for years we received our first phone call from the recipient of a stamped envelope. But to my surprise he was calling because the free stamp that I thought would make anyone smile actually made him mad. He felt like it was our way of saying he had a problem paying his bill. He actually quit just a few weeks later. It was a reaction that I had never thought about. Needless to say after his phone call I stopped putting a stamp on an envelope each month. It made me wander how many other customers I had upset and how many I had made smile. It was a reminder that you never know how anyone will see things. All you can do is enjoy  your half full glass of milk.
