Just that sweet little mystery that breaks my heart
Just that sweet little mystery makes me cry
O that sweet little mystery that's in your heart
It's just that sweet little mystery that makes me try.

My friends all tell me that I look so sad
They don't need to ask me why
They know the reason that I feel so bad
Since the night you said goodbye
It's not the letters that you just don't write
It's not the arms of some new friend
It's not the crying in the dead of the night
That keeps me hanging on, waiting for the end.

Just that sweet little mystery that's in your heart
Just that sweet little mystery makes me cry
Oh that sweet little mystery that's in your heart
It's just that sweet little mystery that makes me try.

I watch the street, I watch the radio
I don't need to turn it on
Another friend comes by and tries to say hello
Another weekend's almost gone
It's not the letters that you just don't write
It's not the arms of some new friend
It's not the crying in the depth of the night
That keeps me hanging on, just waiting for the end.

It's that sweet little mystery that's in your heart
It's just that sweet little mystery that makes me cry
Oh that sweet little mystery that's in your heart
It's just that sweet little mystery that makes me try.

The time is flying fast, and I don't care
To spend another night alone
I want to see you, but I don't know where
Till then I'm walking on my own
It's not the letters that you just don't write
It's not the arms of some new friend
It's not the crying in the depth of the night
That keeps me hanging on, just waiting for the end.

It's that sweet little mystery that's in your heart
It's just that sweet little mystery that makes me cry
Oh that sweet little mystery that's in your heart
It's just that sweet little mystery that makes me try.

That sweet little mystery that's in your heart
It's just that sweet little mystery that makes me cry
Oh that sweet little mystery that's in your heart
It's just that sweet little mystery that makes me try.

Sweet mystery, sweet mystery
Sweet mystery, sweet mystery, sweet mystery
Sweet mystery, sweet mystery, sweet mystery
Sweet mystery, sweet mystery, sweet mystery.
