Bertrand Russell wrote that if people told each other 100% of what they think nobody would be friends with anybody.
Somebody said to me that what we think, say and do coincides just sometimes.
I was also told that some of the most interesting things are left unsaid.
I have to admit that these opinions give me certain claustrophobia at times. I try not to think about it too much and to keep in my pockets the important things that people share with me from their minds.
