And I do mean everywhere. Walking to the train station, people walking ahead of me smoking and I can't avoid it. Walking into the train station, at least half a dozen people desperately puffing away before they have to get on a train for max. 25 mins. Breathing out the last cloud of smoke as they get on the train and then their breath stinks up the carriage. Lighting up as soon as they leave the station at the other end. Walking from the tube station to work. Outside the building entrance when I go out for lunch. Same story on my way home. When I'm at home, can't have the balcony door or any windows open as other people's smoke wafts in. If it's not cigarette smoke it's that sickly sweet vapour. I just hate it so much, and I'm so aware of how bad it is for people - and smokers choose to do it, the people around them have no choice about breathing it in. If it were up to me it'd be illegal.
And please, please, no ridiculous comparisons to exhaust fumes (not that I drive anyway). Cars etc at least have a highly useful function, they get you from A to B. Smoking has literally not one single redeeming quality to make it worth all the negative aspects.
