Essays / I need to write about "an unforgettable event" - ideas wanted [8]

THANKYOU VERY MUCH!!

Hmm. I'm thinking of writing graduation day as my 'unforgettable event'.
i can't think of any introduction that i can speak for 1min :(
As i'm doing a narrative speech for at least 3mins.

for introduction, other than asking the audience questions.
what other things that i need to do so that i can get the audience's attention?
