I'm Only Human

Why is it there are people that they can't smile for you if you're in a happy moment? Is it a burden for them to see you smiling. I really don't understand why they will let you feel down in times of your up's? And in times of your down's, they were smiling secretly. I am only human, I know how to appreciate things either small or big things that I received in life. Not everybody has opportunity like this, who am I if I don't know how to appreciate things? Did you know that all of this things is not ours? God owned everything, our life and everything is just temporary. We have to enjoy life on earth. Try to be happy when you saw your friends, relatives, brothers and sisters are happy. Be thankful to the Lord for them. God bless guys!
