Meaning of "p.s."

Hi,

many of films name contains the expression (p.s.) what is meaning??

is it thing related to love??

waiting for your replays

P.S. stands for “postscript”. It is usually written after the signature of a letter. It has nothing to to with love although I believe you may have seen it in a movie entitled “P.S. I love you.” An example:

Dear Abby,

I have finally arrived in Iceland after a long flight. The people here are wonderful and the food is just delicious.

Love, Tim

P.S. It’s freezing here though.

thanksssss
right … I were meaning this film …

I got it now…
