Never complain about your children to your friends and family, especially when those friends and family don’t complain about their kids to you.
You are your child’s ambassador. It is your job to promote their image publicly and discipline them privately.
Their children are just as challenging as yours and maybe even worse, but they protect their children from you. Meanwhile, you are so foolish that everything you child does wrong will be broadcast by you.
Even Christ praised and defended His disciples publicly, but rebuked them privately. Learn from your Saviour.
