Birthday Wish

Once upon a time, in a kingdom faraway, wishes are being granted to children below 7 years of age. If you were one of them, what is the one thing you would have asked your genie? Just one. Would you know what's best to ask at that age? or would you later realize how you wasted that one chance... the only chance to get what you truly desire.

Or will it truly be wasted?

What happens if your wishes contradicts another persons wish? Will that be a sign that your destinies are meant to cross?
