Fools all have the same feature, that is, they are more likely to feel satisfied. My friends and I are not on the same level except in knowledge, so we can't have in-depth communication in many cases, and we can get along well when fighting. And you will trust them very much, which is very important and precious.
So, I don't think it's stupid to make friends with fools. This fool is really stupid to treat you as a friend, but you don't make friends with TA because others are stupid. This is really stupid.
