HELP!?! SPEECH DUE TOMORROW, HELP! PLEASE!?
well, how too is too vague, what can it be on? anyone? how to.. wash a dog? the outline is always the same, introduction, then the meat of the speech, then conclusion. theres no need to hesitate, just relax yourself and deliver a fine speech, theres NOTHING to it. i did about 20 speeches this semester alone. you get up there, make eye contact with various parts of the room or people throughout and deliver the best you can. dont know what else i can say. just do your best.. (or be sick tomm lol)
