My Worry

I have especial frends who share almost university life. We selected same classes, and study cooperatively, of course after school when we have no other schedule, gahther to do something enjoyable. In last spring vacation, one of us bought a car. When we plan to play, or to eat dinner somewhere, he always drives us there. Thouth his kindness is really nice, it sometomes makes the rest of us annoy. When he drives with others, he is a safety-first driver, but when alone, he becomes a racing driver steering the car with terrible speed...in a word, our driver is a speed freak!! Because of this, if he is absent, the rest of us tends to think that a bad thing would be happened to him. In addition, he rarely return our calling and mail.This is my worry. Today, he didn't appear at the first class, reading class...Please come as soon as possible!!
