It is childish to eat primarily or only to please your tongue.

It takes maturity to admit that you are wrong, especially when you are right.

A man whose mind has completely left childhood behind would not be surprised if he were to walk in on his wife having sex with her father … or with his mother.

Some people’s immaturity is intensified by their stupidity.

Most adults’ minds are still teenagers.

We often betray our arrogance or immaturity by asserting that we will never do something bad that we are capable of doing.
