It was addressed, "Mom" With the worst premonition, she opened the envelope and read the letter with trembling hands: Dear Mom, It is with great regret and sorrow that I'm writing you.

I've been finding real passion with John and he is so nice - even with his skin diseases, piercings, tattoos, beard and his motorcycle clothes. But it's not only the passion mom, I'm pregnant and John said that we will be very happy. He already owns a trailer in the bush and has a stack of firewood for the whole winter. He wants to have many more children with me and that's now one of my dreams too. John taught me that marijuana doesn't really hurt anyone and he'll be growing it for us and trading it with his friends for all the cocaine and ecstasy we want. In the meantime, we'll pray that science will find a cure for AIDS so John can get better; he sure deserves it!! Don't worry Mom, I'm 16 years old now and I know how to take care of myself. Some day I'm sure we'll be back to visit so you can get to know your grandchildren. Your daughter, Judith PS: Mom, none of the above is true. I'm over at the Jenny’s house. I just wanted to remind you that there are worse things in life than my report card that's in my desk drawer. I love you! Call when it is safe for me to come home.
