become a good listener.beside my friends who need me.become an available person for them for all of my condition.as their rubbish bin.those are one of happiness in my life ^^.I'm sure,I always become a person like that,because I know the feeling when we need a person beside us,but there are no one available,their busy with their own bussiness or another reasons.and I won't you feel the same like me.that's the lesson that I have learnt.
