The key of happiness is..."Teegee,Teegee" "Que sera sera" "Everything's gonna be alright""Whatever Will Be, Will Be" "Every cloud has a silver lining" and..."Ob-La-Di, Ob-La-Da"Molly's philosophy of life is inherited by the daughter, I think.Don't you think so?Life goes on how the life goes on.If you want some fun, take Ob-la-de Ob-la-da!Special thanks to this site↓.
