There's a lot that bothers you, a lot that angers the deepest part of your soul, a lot that you really dislike, but the wisest act in all of these kinds of situations is that you do not always blurt it out. You do not always release all this negativity. Specially, if it is just over a petty little thing. Not everything is meant to be addressed. Not everything is meant to be confronted. Not everything is meant to be approached the moment you find a mistake in it.
Sometimes, someone's respect is more important then letting them know what were their mistakes. Sometimes, it's important that you ignore, rather then build up flames for a really tiny missed detail.
Unfortunately, a lot of us forget that. Not everything should be said. It only brings disrespect on both ends. Sometimes, love and politeness corrects more mistakes then anger and attack. Not only that, it brings more respect in hearts. If everyone starts understanding this, the world will be a little more brighter.
