Green Day- "Good Riddance (Time Of Your Life)"

"It's something unpredictable, but in the end it's right!.
I hope you had the time of your life!.
So take the photographs, and still frames in your mind
Hang it on a shelf in good health and good time
Tattoos of memories and dead skin on trial
For what it's worth it was worth all the while" !.!.!.

OR

Vitamin C - Graduation (Friends Forever)

"These memories are playing like a film without sound
And I keep thinking of that night in June
I didn't know much of love
But it came too soon
And there was me and you
And then we got real blue
Stay at home talking on the telephone
We'd get so excited, we'd get so scared
Laughing at ourselves thinking life's not fair
And this is how it feels
As we go on
We remember
All the times we
Had together
And as our lives change
Come Whatever
We will still be
Friends Forever" !.!.!.Www@QuestionHome@Com
