A chinese movie

there was a movie once that my mum told me about and i shall share it with you

Its basically about a married couple, the husband treated the wife so well, but one day the wife leaves the husband for a younger more "interesting" man.
When she leave her husband he is heartbroken, however he still loved the wife, so he writes a book for the new man, a book with the very details of his wife, whats her favorite foods, what shes allergic too and what to do when shes angry.

And that is love.

I find when you love someone enough you cant get angry at them you can get temporarily annoyed but not angry. Because you dont want to fight with them, being angry at them probably hurts you more than them .
