"It's nicer to think dear, pretty thoughts and keep them in one's heart, like treasures.

I don't like to have them laughed at or wondered over.

And somehow I don't want to use big words any more.

It's almost a pity, isn't it, now that I'm really growing big enough to say them if I did want to.

It's fun to be almost grown up in some ways, but it's not the kind of fun I expected, Marilla.
There's so much to learn and do and think that there isn't time for big words.
