You've had a hard day. You were overhelmed so when you came home, you let all emotions out

You sat on your bed and tried not to cry loudly but Simon heard you anyway. He sat next to you, hugged you and rocked you as he started singing

"You are my sunshine, my only sunshine. You make me happy, when skies are grey. You'll never know dear, how much i love you. Please don't take mu sunshine away..."

In your childhood, this song calmed you down, so he hoped it would work this time too
