Loving parents often struggle with giving consequences while at the same time protecting their child from consequences that are natural. For example protecting them from school rules while eliciting yelling, punishment, and lectures. If a lesson can be learned and you don't have to be the bearer of the consequences, why be the bad guy?
Also, never protect from a consequence or give a resource if you are going to resent it. If you are expecting a certain reaction you will probably be disappointed so save the relationship and protect yourself from resentment.
