something about love

I like reading the story about the love between father and son, especially the deep love behind the beat, or I’d like to call it spank. But to be honest, I couldn’t understand it very well. I believe that if I were Shou’er, I can’t forgive the father.
Somebody tell me, I am a lucky girl. I have a happy family, both my parents love me very much, and because I am the smallest one in my big family, my sisters, brothers, aunts all of them love me. So they laugh at me that I don’t understand the love from the son to the father.
As I read this story, I don’t hate the father, but meanwhile, I can’t forgive him. I could forgive that he abandon Shuo’er and his mother, for I have seen his action to compensate for them. However, I don’t know why he doesn’t revenage for his wife and son’s death, even when the murderer is his brother. Who is much more important in your heart? You have give up your wife and son once, you will give up them once again! Can you escape from your own conscience? As to Shuo’er, he wants to get togher for his father for several years in deep his heart, so maybe he can’t decide to hate his father, but that not means he isn’t broken. When the heart is broken, it couldn’t repair.
I have a friend, who is thrown away by her mother when she is just 2-month old. It seems that she is happy in her bring-up parents family, actually she is self-debased in her heart. During the 20 years she grows up, her father sometimes come to see her and give her some gifts, but her mother, never have seen her even once. Now she has a good work, and earns much much □, her mother comes back to find her, and tell my friend how hard she is, and wants my friend to afford her the □ for her daily life. Why? How dare she say this? What makes me much more angry is that she has a son with another man, the son is just younger 1year than my friend. We are women, no matter a girl or a mather, we know just younger 1 year means what has she done that year! This mother also has another daughter with another man, who is not my friend’s father, nor her son’s father. She demands my friend to help her son and daughter. What do you think who you are? My friend gives her mother much □ and let her live in her home. However, if I were her, I think I’ll kill her, at least, I’ll never call her “mother”. She doesn’t know what does mother mean!
The story between Shuo’er and his father remind me of my friend, so the same stories makes me very upset. Maybe go out and never come back is the best choice for Shuo’er, in my heart. If he forgive his father, how would he meet his mother and brother?
That is my opinion, no right or no wrong, just my opinon. Actually, what is true love between father and son?
