“The secret of contentment lay in ignoring many things completely.”

“...and I went into the garden and lay down and looked at the stars in the sky and made myself negligible.”

“Sometimes we get sad about things and we don't like to tell other people that we are sad about them. We like to keep it a secret. Or sometimes, we are sad but we really don't know why we are sad, so we say we aren't sad but we really are.”

“And Siobhan says people go on holidays to see new things and relax, but it wouldn’t make me relaxed and you can see new things by looking at earth under a microscope or drawing the shape of the solid made when 3 circular rods of equal thickness intersect at right angles. And I think that there are so many things just in one house that it would take years to think about all of them properly. And also, a thing is interesting because of thinking about it and not because of it being new.”

“And it's best if you know a good thing is going to happen, like an eclipse or getting a microscope for Christmas. And it's bad if you know a bad thing is going to happen, like having a filling or going to France. But I think it is worst if you don't know whether it is a good thing or a bad thing which is going to happen.”

“...most people are almost blind and they don’t see most things and there is lots of spare capacity in their heads and it is filled with things which aren’t connected and are silly, like, “I’m worried that I might have left the gas cooker on.”

“The world is full of obvious things which nobody by any chance ever observes.”
