Father/Son

A father passing by his son's bedroom was astonished to see the bed was nicely made and everything was picked up. Then he saw an green envelope propped up prominently on the center of the bed. It was addressed, "Dad".
With the worst premonition, he opened the envelope and read the letter with trembling hands:
Dear Dad, It is with great regret and sorrow that I'm writing you. I had to elope with my new girlfriend because I wanted to avoid a scene with mom and you.
I've been finding real passion with Mariel and she is so nice-even with all her piercing, tattoos, and her tight Motorcycle clothes. But it's not only the passion dad, she's pregnant and Mariel said that we will be very happy.
Even though you don't care for her as she is so much older than I, she already owns a trailer in the woods and has a stack of firewood for the whole winter. She wants to have many more children with me and that's now one of my dreams too.
Mariel taught me that marijuana doesn't really hurt anyone and we'll be growing it for us and trading it with her friends for all the cocaine and ecstasy we want. In the meantime, we'll pray that science will find a cure for AIDS so Mariel can get better; she sure deserves it!!
Don't worry Dad, I'm 15 years old now and I know how to take care of myself. Someday I'm sure we'll be back to visit so you can get to know your grandchildren.
Your son, Tom
PS: Dad, none of the above is true. I'm over at the neighbor's house. I just wanted to remind you that there are worse things in life than my report card that's in my desk center drawer. I love you! Call when it is safe for me to come home.

Joseph LeConte

Died 6 Jul 1901 at age 78 (born 26 Feb 1823). American geologist who was a universalist in the scope of his scientific writings. As a founding member of John Muir's Sierra Club, he spoke fervently for broad preservation of California forests by government and wise use of timberlands in private enterprise. He was one of the earliest advocates of contractional theory of mountain formation. LeConte accepted the theory of evolution about 1874, becoming one of its leading proponents and a writer able to reconciler the idea with religious thought. His Sight: An Exposition of the Principles of Monocular and Binocular Vision (1881) was the first treatise on physiological optics written in the U.S. He was an ardent camper, and his death occurred during a trip in the Yosemite Valley. He was the younger brother of John LeConte.
