we all know how much smoke SUCKS when it gets into our lungs. well i was just out with my friends around a fire in their back yard when a bunch of them decide to smoke some cigarettes , i don't have a problem with them giving themselves lung cancer, but i cant STAND the smoke. I walked away coughing and wishing i had my vest to shake out all this smoke getting stuck in my lungs, while they inquired "why are you being so anti-social" ughgh i can't stand when people are ignorant about smoking, even if i didn't have cf they don't realize people around them are inhaling their gross cancer-smoke and some DONT LIKE IT. what do you guys do when there's people around you smoking? whether you know them or dont?
