I was thinking lots of things, but most of them needed to stay thoughts, not words.
I think I've developed, as many people do, this sense of, 'Don't say the wrong thing, or else people will point at you and laugh.'
Everything I think of now is too rude to actually say.
It is possible to have words come to your mind, and still refrain from speaking them aloud.
I have the impression that every word is a word too many. I'm constantly holding myself back.
Many people in the intellectual elite are very scared of shouting. They insist on very quiet murmurs.
