Why I can't be smart like my lil nephew?

This is what happened today in the living room
My lil nephew: can you give me some money plz ?
Grandma: in your dreams I just gave u money yesterday!
Lil nephew: okay I will go wear pajamas now...
Grandma: why? It's too early to go to sleep.
Lil nephew: but you said in your dreams and I need money so to bed!!!
Grandma (laughed and gave him money)
Me:.......
T.T if it was me she would have just yelled at me for wasting money
