Why there's a word "Waiting"?

It sucks when you already prepared yourself for somethin big and it never come. That's what happened to me..
I've been waiting for the whole semester to finish my thesis and graduate from my campus. And when the day has come, they make it complicated by their silly system.
I'm completely ready for my thesis defense but I have to deal with some knick-knacks that I don't think necessary to think of right now.
I just wanna graduate as soon as possible, how's that really difficult to be understood?
