Life is so strange
With it's up and downs
And today's hero
May be tomorrow's clown

Friends keep on telling me
That I'm a fool to be
So in love while
You're just having fun

I'll spend each lonely night
Longing to hold you tight
Morning finds me
Crying to the sun
[ Lyrics from: http://www.lyricsfreak.com/d/dion/havin+fun_20795301.html ]
But I'll find somebody new
And I'll get over you
Then my broken heart
Will hurt no more

Someday you'll realize
I was the one
Then you'll be crying
While I'm having fun

You know
Someday you're gonna realize
That I was the one
Then you'll be crying
While I'm having fun
