it's my life

Grandma, who was living with her daughter's family, let her 11-year-old grandson in from school. "What did you learn today?" she asked.
"Sex education. All about penises and vaginas and intercourse and stuff," he replied matter-of-factly.
The old woman was shocked and reported the conversation to her daughter.
Her daughter replied, "Mom, this is the Nineties. These days it's all part of the curriculum."
A few hours later, the grandmother was reading when her daughter announced dinner was ready. Grandmother walked past her grandson's bedroom and noticed him on his bed, vigorously masturbating. "Sonny," she said, "when you're finished with your homework, come on downstairs to eat."
