Respect is something that has to be earned in my perspective. Teachers, parents, and any authority figures are considered people who are supposed to be given respect. Not only are people supposed to be given respect, but their decisions are also supposed to be respected. I believe respect can take years to earn in come cases.
My first impressioncan also be my last impression so I would try my best to make it worth the time. Also that first and last impression can tell alot about you as far as being respectful to the that certain individual. Respect is easier to lose then it is to gain. It can be lost by a word or a decision that you have made if others do not agree with it. People can spend their whole lives thinking of ways to earn respect, but unless you do something or put effort into getting respect it will not be earned.
