Let me tell you something, as a student pursuing a certain profession, we’re expected to have a knowledge regarding to public speaking and may apply it as early as today since we have accomplished different kinds of English subject. We have gained certain confidence enough to apply it in any various of the event. So don’t make an excuse why your attitude and actions have greatly impacted the whole event. No one will accuse of you of anything, but your proper manner. Nervous is already given that we all feel it when the spotlight is directly on us, which led to wrong grammar, or shaky words (sometimes, well definitely not the entire time), no eye contact with the audience and even the pitch of our tone. But that’s fine, we’re on the same page. Not all the people can be a perfect public speaker for any event. But we can be a good public speaker by doing the flow the script directed to us, proper addressing and gratitudes for others, and last but not the least by taking it seriously. You have gone mad by commenting things that are not appropriate, saying disrespectful phrase, and laughing for no reasons.
