late at night lyrics

I walked in on you
I couldn't believe my eyes
I forgot to knock and I apologize
But I can't forget what I saw

I always wondered if you had a darker side
You wear a smile but your eyes are red
Like you just cried
Now will you explain?

By day you wear your happy face
Everybody thinks you're perfect
They don't know much about your pain

Late at night no one can see
You cut yourself to get back at me
Late at night I try to understand

Your friends all call you first
When every little thing goes wrong
They know that they can count on you

But you don't call on them
When you need a little help
You work it out alone

Late at night no one can see
You cut yourself to get back at me
Late at night I try to understand

While I'm wishing on the stars
You're collecting little scars
Late at night what did I do wrong
That you deserve to bleed?
Tell me just what should I do?

Now I know your secret
I won't tell your friends at work
I won't tell your favorite niece
I won't tell your mom and dad
I won't tell anyone why you wear sweaters when it's hot

How will you explain the scars to your kids?
Will you lie to each new person in your life?
