Your children are brats. They are walking all over you. This is your fault, and our patience is wearing thin.
Care to know the psychological effects of spanking in my own personal experience? Good behaviour and consistently happy and enjoyable family outings. Full stop. Spankings are not beatings. One swat on the bottom is a spanking. Somewhere out there on a slippery slope, a small, whiny special interest group has turned otherwise rational people into spies who call child welfare if they witness a bratty half pint being disciplined by their own parents. I challenge you to reason with a 4 year old- it is like reasoning with a stick. If I acted out while on an outing- guess what? The outing was over. Lesson learned.
Now, back to you, ma'am. Just because mommy needs a new blouse, doesn't mean the rest of the world should be subjected to the screeching and flailing and awfulness of your progeny because of YOUR poor parenting skills.
There are so many good kids out there that I meet every day (and great, patient parents). And well-behaved kids. And no, I realize this is not the library in an adults only complex. Kids will be kids, but your kids are giving kids a bad name.
