Bringing a baby no more than 4 years old out for a 9.45 pm movie doesn't say much about your parenting skills. Letting the baby scream his head off in the cinema for a good 5 minutes doesn't say much about your civic mindedness. Screaming back at the many voices hollering for you to take the baby out of the cinema simply shows how stubborn you are. At least you lot have the brains to leave the cinema as soon as the credits started rolling...
