You know what a good birth control would be? Spending time in a house with teenage boys. My experience with teen girls is nearly 0, outside of remembering myself at that age and frankly I was perfect, but boys? It is all I can do right now to not freak at my lovely first boy who just said "screw you" because I dared to ask why he was being rude to his younger brother.
But in the next breath asks me to front him some money to help fund his paintball passion.
Colicky newborns and terrible twos have NOTHING on the evil that resides within those long lanky bodies.
