Some tots on parenting

Should we expect our kids to exactly follow whatever we said? In some way, the kids have their own ego, didnt want to listen to parents and want to do things in their way. Thats why we always heard ppl say 'kids love to explore, but not on the way adults do'. Of course you cant treat the kids like you treat adult, well in most cases though. After all, do not ever call them stubborn or ungrateful, what more harsher words like stupid, naughty, bad, and other similar meaning.
