If you appreciate the kindness shown you by others, say it with actions as well as words.
The people who enjoy the greatest financial and personal success 
in life are those who build lasting relationships — with business 
associates, friends, co-workers, and others. They take the time and 
trouble to stay in touch, and they make sure that when someone does a 
good deed for them, they respond in kind. Build your network of personal
 and professional friends by taking the initiative and being a friend.
~Napoleon Hill
