And how does one hang out with their child when their child is supposed to be at school?
I agree you shouldn't worry so much. But you should strike a balance between being with your child and not being with your child. Saying, 'work less, be more active', smacks a bit of the old Sank Tea Moany, and really is a dig at parenting styles. The guy just found out his kid isn't quite getting the full foreigner experience he wanted it to have. Plenty of the world's kids have grown up just fine without a helicopter parent. And I would certainly not advise spending more time watching the idiot box with your child.
It's pre-K isn't it? My kid went to the first year and skipped the second. Work less? Sure. If he doesn't have a 300K bill to pay he can do that easy. Not sanctimonious at all.
And I'll need concrete proofs that you were a child, please, and that you were not born in Kenya or any other communist country thanks.
