Why they like to gambling?

Yesterday night, a friend that never sms me suddenly send a message to me. He said: "Can u lend me RM100? Don't tell any body." At the moment, I knew what happened. I'm asking my wheater I should lend him or not. Finally, I rejected him. I rejected him not because I have no money. It is because this is the time that give him a lesson.

Today, when I searching for him at class, he was absent. I knew from my friends, he owe others people money because of gambling. How can it be? He is only 15 years old. That didn't suprise me. The suprising thing is the amount he owe is about RM 3000 just because of gambling. I feel a little bit pity in my heart, wheater I'm right or not. Everybody tell me that he is borrowing money from everyone. No body help him. His family also don't know about this.

Should I help him? No! Sound from my heart said that. I had told him long time ago to stop gambling. We should give a lesson to him. Not only me agree with this. All of us agree strongly.
He should tell his family. Now, we just wait and see. What gonna to happen next? I'm ready for your comments. Tell me what should I do.
