angel or devil???

At times, you would think that you know a person so well, we sometimes say ‘i know him/her inside out’. But the fact remains, you will never know a person, friend or family, close enough to know inside out. There are people out there, that sometimes could be so ‘evil’ yet look ‘angelic’ you can never judge a person by the appearance (yea never judge a book by its cover). There are people, out there, who deliberately mislead you to believe that they are your friend, and then after a loooooooooong time, you discover, the person is just a monster in disguise!!! Be careful who you trust and the extent you are willing to share. Because, you never ever would know whats cooking in some1 else’s mind.
