a person who smiles a lot doesn't mean that the person is happy or optimist.. it can be the opposite.

everyday, the same... class, office, dinner den slp gua..
playing and chatting and laughing are all the ways to help you to hide all the unhappiness and the sad things. everyday, i know only how to hide all the things and only know how to avoid thinking but when the time which u will be alone comes, everything seems so sad... u feel so alone... and nothing you do can help.. nobody will realise and know how many things and experiences that you have encountered and endured in the past. all they can see is the one unmatured and a sohai person who keep making people laugh and she do not know anything. however, they do not know that those kind of people are the one who encountered sth and they are scared to lose sth and this might e the way for them to prevent from losing something that they care. sometimes, one might be too proud for you to accept, what u do is to hurt them more by words but you do not know that this is the way they try to protect themselves.. sometimes, one might be too sohai and it seems that they do things without thinking, what you do is just to laugh at them, but you do not know that this is the way they avoid something and they want to make you to care for them as they care for you... sometimes, they smile a lot and keep laughing, what you do is just to say that they are just too stupid to laugh at those things which are not so funny, but the things is that you do not know if they do not do that, they might not have the time to laugh so happily.. they ae just finding and appreciating the time that they can laugh and smile happily, even it is just that moment that they will forget everything to really have a laugh.
don't ever look down at someone who seems so stupid as they might be the one who encountered more than you do and they might be the one who lives more miserable than you and do not laugh at those people but to care for them bcoz what they want is the love and care of yours and the person who open up their heart for you~~ you do not need to do many thing for the people as they believe people too easily~~ and if you betrayed the person, you will never ever get the person's trust again and you will never the so gud wif that person again~
