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
(Sweet my-, sweet my-, sweet my-, sweet my-)

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 (sweet mystery)
It's not the letters that you just don't write
It's not the arms of some new friend (depth of the night)
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
