"Because never in my entire childhood did I feel like a child. I felt like a person all along - the same person that I am today. I never felt that I spoke childishly. I never felt that my emotions and desires were somehow less real than adult emotions and desires." —Orson Scott Card, Ender's Game

"Why don't kids play outside nowadays" Look out the window. What outside? How do they play there? They could go to a park, but how do they get there? They could play in the city, but would that be safe? They could go bush, but how? They could play around the neighbourhood, and then what, make a tiny bike ramp by digging and gathering a bit of dirt from a drain and then get reported and then have the council send letters to everyone living in the area to ask if they'd seen the kids and if so please say who they are and then put up signs saying that the area (ie the big drain they got the dirt from and the bit about it) may be under surveillance despite there not really being anywhere to put cameras? (that last one is a true story from where I live btw)
