我不会赌我没把握的事

My brother sets password to his mobile phone. I told him I can be a very good code breaker. Well sometimes is really by luck but mostly is because most people passwords are set somehow related to them. Especially handphone when it is only limited to 8 numbers.

I tried two times and I manage to break his password. I didn't want to tell him at first. But he placed a bet. So I bet with him. However he cheated, he went to the toilet to change his password. When he came back, I placed my bet and it wrote invalid password. I knew what he had done. So I confronted him. Actually is not about the money but about the lies. He lied saying that he had change the password this morning when I am able to break the password few minutes ago. He told me that to log in to the message inbox requires two passwords which I knew there wasn't. I told him to prove it in front of me. He held his handphone and pressed, keeping the phone away from my sight, trying hard to prolong the time. I know what he is doing through the reflections of his glasses. I think he would never ever knew, whatever he do including typing the new password can be seen through the reflections of his glasses. But I decided not to tell him. Since he is a big liar.
