7. Sneering at noisy children (or their parents)
My kids are noisy sometimes; it’s true. They’re all 4yo and under; I’d probably be concerned if they sat still and quiet for an hour. Given that kids are equal to adults, having every right (from baptism) to be present for the Mass, and given that folks who don’t have the responsibility of wrangling children during Mass and training them to be quiet are not so deserving of sympathy as the parents who do, might I suggest that you thank God for the little buggers and parents who actually care to train them in the faith.
