No, they have not. Or if they have, they have personally abrogated any responsibility for cessation of the infant's crying to another; and if they haven't done that, they are sure their baby is allowed to cry, since other parents (strangers) allow their kids to cry, and this will show them.

In short, they have not paid their dues in having to quiet an unhappy bawler, and cannot share in that frustrating moment of common humanity. They are innocents who have not seen the elephant, and we may grant them a certain leeway in their complaining; as they grumble, we cannot help smile at them. There is a certain freshness to their naivete in the ways of life. They are boys.
