Think again.

If someone has to continuously tell people that he or she is grown and mature then he or she clearly isn't.

Same goes for being real and modest, etc etc...

Actions speak louder than words. If someone wants people to actually believe that he or she are said things then I suggest that person starts acting like it. Don't go around proclaiming that you're this and you're that but you aren't doing anything to prove and back your word up.

If one thing is true about people it's that they're all talk and no action.
