No One Knew

In truth, no one knows I sing myself to sleep.
Is that because I don't want them to know?
Or because they don't?

I only sang to try and think of better things,
When the pain became too much,
And I was truly all alone.

Perhaps that's why no one knew,
I have habit of crying when I sing,
Because it's an instinct
Of endless nights repeating the same tune.

No one knew,
Except now you do too.
