Those Squarking kids will be paying taxes and supporting us all with public services when we are old.
Be a little bit tolerant - 99% of the time the parents are doing their best to keep things down to a dull roar esp. with babies.
I must admit I am less tolerant of rampant undisciplined 4 y.o. kids than of 6 month old babies who have no idea of what is going on.
