introduce a movie i want to introduce a movie named"A Sad Story Than Sadness" ,which is extremely moving. the first time i saw it was two years ago,and later on i saw it many times. and there is a scene in the movie ,which i am totally crazy about. that is when actress has to marry a man she does not love at all,the actor ,who has the incurable disease, just gives her a pat on her hand and turn back to go out of the wedding hall.He knows he will die,so he hands her to another guy who can accompany her instead of him. every time i saw that scene ,i had a feeling that something came into my heart---the true love in the world. i cant help crying. from then on ,i always like to pat my families and friends on their hand. they all dont understand what im doing.they feel it is strange. but i just smile and still pat with deep sentiment. this is my way to say"you are an important one in my life". Please help me corret this article and could you please tell me what sentences would you make if you want to express the same meaning?
