I'm probably biased, but absolutely agree, and take it further.
It used to be parents would take their kids outside and punish them, and I'm sure many are, but I personally have never seen it happen. Libraries are egregious, but other places too.
I get it. You're tired, you're overworked, parenting is hard. But they are you're responsibility. Libraries are not childcare. Letting them run through grocery stores is not parenting. Sitting in a nice restaurant letting you child scream is not parenting. It is the parents job to teach them when it is and isn't okay to run around and scream, and if they can't handle it that's fine, but they don't belong there yet. Take them outside. That's your job.
I still remember I was screaming and screwing around in church and my mom told my dad to take me outside. I remember because it was well over 90 degrees out and we're sitting in the car. I finally chilled out and said "dad I'm hot". I'll never forget what he said
Yeah well I'm not too but it's you're fault we're both out here.
It's not comfortable being a parent, but that's the role you're in.
