Have the "Fuk it" attitude, i hate presentations/speeches/dramatic presentations too, dramatic presentations are the worst because you have to be...well...dramatic!..frankly i suck at that.
But what can you do?
Get it over and done with, i mean, you can either be a pu$sy and refuse to do it while the whole class laughs at you, or you can get the fuk up there and do what you have to do, and earn some respect.
Good luck.
