Respect Is Earned Not Asked

Life is too short to be creating enemies when you least want it.
I remember this senior in an event in my college I'm currently participating. He's so... Judgmental with our work. Like its never good enough and he comments our work like we've done serious crime offenses. He always failed to realise that should he have given his opinion early on in the task, we could have avoided major problems that arisen due to our lack of experience. He's ignorance is the reason why we keep making mistakes since there is no one to guide us properly. And when the job is done after hard hours put in by the volunteers, he sneers and remarked that everything we did was wrong and that we should have asked him first what was supposed to be done. But we did in the group email link that we use a our main conversation. At yet remains silent until the very end to annoy those who have worked so hard to make an event successful.
I've personally dealt with him where he discarded my poster designs saying it would not get the reader's attention and I should re-do. Then he continued to comment about the taglines I created without giving his own opinions of how to improve the situation. And I despise him for him. Because he never once offered constructive criticism. Instead he went ahead to crush our fighting spirit and what's left of it.
I learnt a great life lesson from his unacceptable behavior. Respect could never be asked. It must be earned instead. The way you treat people will forever be etched in their minds. And if you're rude or arrogant, believe me no one will respect you. If you want to help you can offer some solutions to your negative remarks. This will prove that you're concern with improvement and not just about commenting maliciously at other people's work. That would just create a bad reputation for you.

I hope when I'm in charge of an event I'll always stay courteous and polite.

As Michael Buble once put it, "the good guy gets ahead miles in front of everybody else who's rude"
