Air apparent: A Tinley Park teen is suing her school. Heather Morrin, a junior at Tinley Park High School, has asthma; when classmates smoke in the bathroom and stairwell, it's hard for her to breathe, her lawsuit says. The smoke has triggered sev-eral asthma attacks that have sent her to the hospital, her mom says. The principal says the school does the best it can to enforce its rules against smoking. We'll see what happens when the smoke clears.
