Adults: why do you blame our generation?

every time an adult lays their eyes on a teen 17,18. They always feel were the downfall of the world, were the ones that drink & drive, we're the ones that spread deadly sex diseases, we're the bad influences on their children, we're spoiled, get belligerently drunk everyday and ruin everything for them.. so why do you adults have such harsh views on us? .. we're not THAT bad;) just trying to enjoy our lives before we have hundred bills & mortgage to think about and all of that other stuff;)
