Pretending is an interesting business, practice really makes perfect.
Everyday you pretend a little bit better until one day it becomes so natural and then you don't even have to pretend anymore.
It becomes true.

What about dreams?
Can the castle I practice painting in the sky gain weight each time I dream of it?
Will there be a day when it touches the ground and finally becomes solid and real?
Will you hold my hand and walk into my dream together then?
