~* The Mouse *~

Yesterday night we were at my brother's room. My brother was doing something on his computer. As usual, YJ cannot sit still and watch. He grab the mouse and mouse pad and try to click on it. After a while, we try to take away the mouse pad so he can stop but he ended up fighting with us for the mouse pad because he don't want to use the mouse without the mouse pad. I was wondering, how does YJ know that the mouse need to have a mouse pad in order to function :D When he was playing with the mouse, surprisingly, the mouse never goes out from the mouse pad :D
