cur-mud-geon: anyone who hates hypocrisy and pretense and has the temerity to say so; anyone with the habit of pointing out unpleasant facts in an engaging and humorous manner
You may have heard or read of the Carnegie Mellon University Professor Randy Pausch and his 'last lecture'. He is a 47 year-old man who has pancreatic cancer and is dying. His family consists of his wife and three children ages 6, 3 and 1.
His last lecture was delivered in September of last year and has been viewed by millions on the Internet. This was his approach to saying goodbye.
The Weekend Wall Street Journal for today carried an article written by Jeffrey Zaslow that was very well done, and the actual lecture is available for viewing at thelastlecture.com if you're interested.
