Mine don't either.
Last night, wife and I (just us) are at a neighborhood sushi place that we really enjoy.
Behind me is another family with a baby, probably around 18months old. Happy kid and he's right behind me the entire time having a blast. Kids having a blast are not quiet.
I the only time I actually 'heard' it was when my wife would giggle at the kid or something and while I had him tuned out (easily) I know the kid was making a bit of a racket.
The family behind me arrived right after us, in the restaurant when we arrived was a pair of older folks having their own night out.
As my wife an I are finishing up and preparing to ask for the check a commotion ensues behind me.
One of the older fellows has engaged the father of the baby behind me to quiet him down. He's not politely asking - he's fairly demanding about it. My wife is surprised and I am too. Our neighborhood is full of kids so generally speaking what is happening right now is 'the norm.'
The dad asks rhetorically 'what do you want me to do, he's a baby.' He ends up taking the kid outside and they pretty much left due to the altercation (on his way out the Dad did call the old fart some a POS...so he wasn't 'nice' either) but my wife and I are sitting there just watching aghast at the scene. My wife even engaged them saying "It's EL SEGUNDO for crying out loud - EVERYBODY had kids!" And one of the ladies at the older table responded - 'well, he's not from around here.'
ANYWAY - it was interesting to watch. My wife is 9 months pregnant with our second and was wishing she had the baby so she could have breast fed it in front of the guy (she's crazy as a loon you know).
I know that before I had children I didn't like the loud kids in the restaurant thing but what are you going to do? If parents don't bring their kids to restaurants then the kids won't learn how to behave at one (assuming good parenting here which is what was happening last night). We try to be as considerate as we can but our kids don't have mute buttons and especially the younger ones - feelings and emotions run hot and quick.
I know people hate kids but I hate people so those who hate kids can kiss my butt.
