In my opinion, a mature person will talk with a sense in his talk. He will never go on taking which is of no value. He knows how to point out the mistakes of others without hurting them. He knows what he should talk about and what he should not talk about. But an immature person will go on talking about something or other. A person who has seen ups and downs in his life will have a high level of maturity.
Believe in the existence of God the super power.
Anyways, invariably, people should show their maturity while interacting with other people.
