To forget a friend is sad.
Not every one has had a friend.
And if I forget him, I may become like the grown-ups who are no longer interested in anything but figures...

Grown-ups never understand anything by themselves, and it is tiresome for children to be always and forever explaining things to them.

Then I would never talk to that person about boa constrictors, or primeval forests, or stars.
I would bring myself down to his level.
I would talk to him about bridge, and golf, and politics, and neckties.
And the grown-up would be greatly pleased to have met such a sensible man.

I like babies and I like little children, till they begin to grow up and acquire adult habits of thought and adult abilities to lie and cheat and be dirty.

The reason why grownups and kids fight is because they belong to separate races. Look at them, different from us. Look at us, different from them.
