Past Tense

You used to look at me like I was the only one in the room,
You used to think I was the only one who believes and understands everything you do,
You used to walk with me and feel like you're in Heaven,
You used to say we can overcome whatever challenges life throws our way,
You used to listen to me and thought the world of the things I said,
There was us...
Now it's just you and me...
Two lives separated by a cruel twist of destiny.
