Time Of Your Life - Green Day

Another turning point
a fork stuck in the road
Time grabs you by the wrist
directs you where to go
So make the best of this test
and don't ask why
It's not a question
but a lesson learned in time

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
of good health and good time
Tattoos of memories
and dead skin on trial
For what it's worth
it was worth all the while

It's something unpredictable
but in the end it's right
I hope you had the time of your life
