You see every other smoker do it and you think, what’s the point? and you just throw it away. I can’t carry it in my pocket. If trashcan is in visible sight, I’m ok with walking little bit to get rid of it. But usually it’s the case that there isn’t any good way to dispose the sigaret butt. I remember when I started smoking I never littered the street, I took extra steps to get it into nearest trashcan, but three years later I have changed.
