good god man you could have killed a child!
Little Timmy isnt coming home tonight, said goodbye to his friends and was walking home from soccer practice on that cold rainy night, he didnt hear you and now he's wrapped around your spokes, the parents are crying, the dad turns to drink and hangs himself whilst the mother blames herself for letting him out to play so late, she too turns to drink and ends up OD'ing on crack in a doss house on the wrong side of town...
just think of THAT next time you go for your test, then see if you do 30 in a 20
