A very self-important college freshman at a recent football game, took it upon himself to explain to a senior citizen sitting next to him why it was impossible for the older generation to understand his own.
"You grew up in a different, actually almost primitive, world," the student said loud enough for the whole crowd to hear. "We young people today grew up with television, jet planes, space travel, man walking on the moon, our spaceships have visited Mars...We even have nuclear energy, electric and hydrogen cars, computers with light-speed processing ..and uh..."
Taking advantage of a pause for breath in the student's litany, the "wizened" one said, "You're right, son. We didn't have those things when we were young... so we invented them... you arrogant little twerp!
Now, what are you doing for the next generation?"
