As an adult you realize that there is a time and place for everything.
You can not let your frustration and anger get the best of you in every circumstance. You need to be able to handle situations differently.
With age comes wisdom. It comes to play at that very instant. You no longer let anything or anyone control you as they have before.
You understand that as an adult you are able to move past things easier for the sake of professionalism and peace.
We realize that we do not know the story of the next person and what they have gone through so we understand better why humans are the way they are.
A lot of times people are mean or rude to you not because they want to be, but because of everything they have and maybe continue to go through.
That is why you don’t react over the smallest inconvenience.
Being profesional will only benefit you in the long run.
