Some adults are so self-conscious that they are unable to look, for longer than two seconds, a child or even an animal in the eye.

If an adult has just moved as fast as a child, from crying to laughing, then it is either the laughter is fake, or they are being tickled.

Adults often treat each other as children, and children as adults.

The average adult has had sex innumerable times more than they have formed an opinion of their own.

The average adult hates being treated like a child, unless it suits them.

Most adults are knowledgeable to a child, but ignorant for their age.

With regard to things such as independence, mental capabilities, and sexuality, a very old man is nothing but a gigantic infant with white hair and wrinkles.

Many of the boys and men who are regarded as immature by some females are so deemed merely because they do not want to get married someday … or soon.

It is a sign of immaturity to believe that being older than someone (automatically) makes you more (mentally) mature than them.
