Hangnail - Don't let the sun

When we start to fight and you play your stupid games,the frustration sets in and I just can't think straight.I know that tomorrow will bring a new day.We'll be friends 'till the end, but it won't last that long.What is there to fear, when tomorrow brings a new day?Don't let the sun go down on your anger.When morning brings the sun, I feel better than before.Though last night went all wrong, I can't dwell upon that.If we can't work it out then I will take the blame.We'll be right where we were, another fight's all the same.
