Cute picture...I like that one!
As for the whole smoking deal; people make a much bigger deal out of smoking in the US then they do in most of Europe. TO them smoking is natural, and no one really cares. In fact the idea of NON-Smoking area's is controversial for many places, which could be a big part of why Caroline and Stephanie see no problems with smoking. So whether it is looked down upon in the US, it's not there and it's no big deal.
Also in many places in Europe there is no set age for when buying or selling Cigarettes is ok, so they can't really punish people for selling to minors as they do in Canada and the US (Age 18 in most US States...)
