In a crowded waiting room instead of getting mad at how long you have to wait entertain yourself to help the time go faster. Catch the glance of a young child and give them a warm smile and for the rest of your time waiting they will keep checking to see if you are watching them ready to smile real big as to say "I see you." You won't be able to resist smiling back at them. After several warm smiles that you share they seem to call your name and you finally can get out of that chair. Enjoy a glance and a smile while you are waiting instead of getting angry.
