another hello ?

the worst part is when you say hello, you gotta say goodbye.
In just a short moment, we will all gather in the school hall, shout horray as loud as we can.
Then a moment later, graduation night...
It's hard to imagine the big world out there when I see you guys right now.
It's easy to imagine me reading yearbook with tears in my eyes ten years from now.


Do we really have to say goodbye ?
Or is it true that goodbye is just another hello ?
