child and adult conflicts

As kids we had a lot of conflicts with a lot of adults in our lives, rather it be teachers, baby sitters, our parents the principle, for some of us it could be our step parents. why do we have conflicts with adult if we are suppose to respect them? it could be the way we were raised and grew up, to be rude and spoiled and think the only way to get what we want is acting like a little brat and make conflicts, or the so called friends we hang out with can influence us too.  it could be something you guys aren't agreeing on and you don't like the decision. it can be a lot of things. conflicts will always happen between the child and the adult, it shouldn't and maybe we can change that and learn to agree. or come up with an agreement.
