sorry saddy buddy,everything is not in your control what you think is ok but what happend you dont know is it possible that all thing will happend as you have planned. i dont think so dear,now you only care your parents as a part not with feeling but when you will be father that time you will reliase that what pain your parents bear to cultivate you & this feeling is not pain.it is the feeling when you will understand the reality of parents before that situation you cant understand.which experience or knowledge you have that is only theorical but practical is more deep.
