actually i have very different thoughts on it than all of you.........i really feel sympathy for him
if you see his mental condition and how he has been forced to supress his emotions and desire to liv eup to onther person's desire it is obvious one will turn in to furstrated soul and may be in begining he might have sacrifice everything for his father and brother , he has been deprived of love and care that he needed most in his life and he might have thought that he will gain that from his wife but that also did not happened that had made him bitter and rude....
he has always been asked to given in but never been given back.....
if you keep yourself on his place and than think how difficult it is to bury your own dream and desire and live for other people its not easy....and being elder of the family is not easy that title comes with many responsibility and sacrifice......
yes at times he get rude and bitter but thats way he has turned into or may be as dadaji said pashu has fear of loosing loved once....that's why now he does not let anyone comes near to him.....
actually i have great sympathy for him........because at least he has dignity that when he realised his mistake he ask for forgiveness and he does not have any problem with toasty or anyone else but he has complain against his dad...................
