"Never go to sleep mad"

The other day I was listening to a song by Ne-Yo titled "Mad". In this song he is singing to his girlfriend. According to the lyrics he is obviously in a fight with her and they fight quite often. In the chorus he repeats, "I don't want to go to bed mad at you and I don't want you to go to bed mad at me." This is a phrase that is used a lot and I think many people look over its true meaning. I really started thinking about what it really meant. Since you go to bed every night, I think this phrase is trying to say do not hold on to things. Just let things go because tomorrow is a new day and you don't want to end your old day mad. If you never go to bed mad then in reality your never mad for a long time which makes you and the people around you a much happier. If you never go to sleep mad then you can never be mad about something for a long time therefore you are letting go of all the anger and tension in your life. Maybe things in life make you frustrated or upset but in the end you just have to find the good in life and try to live positively. Don't go to sleep mad. Let go of things that make you upset. Find happiness in life!
