"Why can't you let S play for some more time on the PS3?"
"Why can't S do less homework today?"
"Why can't S have another chocolate?"
"Why can't you read another story to S?"
Mostly, there are certain ulterior motives attached to the demand. For instance, the extra story can be enjoyed by A too. Still the gullible S keeps thinking it's all for his sake. Needless to say, S is basking in all this support. There is a popular Tamil saying,'Thambi udaiyaan padaiku anjaan.' 'A man with a younger brother needn't fear any of life's battles.'
Guess, it is true!
