When my oldest was 8 months old, we were at a restaurant when a loud woman came in and immediately said, "Oh no! Another screaming kid!"(his mouth wasn't even open) My son behaved better than she did.
Fully agree. For me, there is a distinct difference between a brat throwing a Screaming Mimi type tantrum and a happy and joyous child sometimes laughing out loud.
A smiling, happy child is an utter joy ... Brats are not.
