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 I try to understand, your friends all call you first when every little thing goes wrong, they know that they can count on you,
