A matured guy is simply a guy that respect himself and others. it got nothing to do with pocket. A good example is NATH.
I am not sure you digest the poster's request sir. I am defining based on the posters requirements and not in real sense .
When we now talk of a matured guy in the real sense it is someone who lives life based on principles and wisdom. He is calm and level headed. He has the mastery of relating with others and has an independent mindset. His decisions are always responsible decisions and he considers other people.
I equally agree with you that amongst all the active members, our keke napep driver has exhibited such traits. I know one inactive member too that falls into this category. I am sure when he reads this he will know himself.
To cap it all, maturity has nothing to do with age.
