So lets say you're riding the subway and a Mom/Dad gets on with their toddler. The toddler (who will call "Alien") won't shutup. Do you:
a) Ask the parents to quiet him down?
b) Move to the next car?
c) Throw the child from the train and tell the parents that it's for their own good?
d) Go slowly insane, allowing the sounds to meld into one screech?
e) The child is clearly a banshee wishing to be teleported to his real world?
