Flying in to Support a friend

Went to Dallas over the weekend for a 60th birthday party a friend hosted. It was a costly trip when considering the airfare, hotel, gift, dress, baggage and transportation costs.  Plus, I got a nasty cold.  But, was it worth it?  This friend has sent me so many clients over the years that I felt it important to be there for her.  So, it was another investment opportunity that outweighed the costs.
