Let the kid dream
Believe me, your mother will always be there to pull you out of your world of imagination if you are deceiving others as well as yourself by pretending to be something that you are not.
Moms are super best! You will appreciate your mom after a while though it will be embarrassing at the time she does this. Not just only loving you but keeping you credible and modest is part of her duty and she will happily do so.
