It is not my intention to generalise, but it appears to me that most smokers are inconsiderate. They couldn't care less that their secondary smoke affects the health of loved ones (I have seen men smoke while carrying a baby or with a toddler in tow). Many of them throw cigarette butts all over the floor in public places and even down from their HDB flats.   

This exactly happened to me. I live at 15th flr and the top flr auntie just simply throw the cigarette butt down and burn my towel hanged outside. The burn mark is stil fresh as it looked blackish colour.
