penguin: Sitting by the river, Dreaming through my reflection, I wonder what has happened. What has caused this distance? We used to be together, Cuddling close to each other. What came between our beautiful love? I don't know, though I wish to. I can see you now, not alone You're holding a hand that's not mine Where am I? Why not next to you? Why am I away? I don't understand. You're smiling to the fullest. I am not the one making you happy. You are glancing at someone else. Why is it not me? Seeing you after such a long time, My heart sighs again. Something inside me growls loud 'Cause now your hand runs through her hair. I stand some distance well away, But the surroundings disappear. When I look at you, I feel lost inside I wish you back, my angel. There you are, holding her hand, And I am lost, trying to understand. I want you back, I really do, Just to hold your hand And walk with you.
