My friends all tell me that I look so sad;
They don't need to ask me why.
Another reason that I feel so bad,
Since the night you said goodbye.
It's not the letters that you 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 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...
