Answer the question about text:

It became apparent that nobody really pays attention to that part of cigarette ads ... everyone smokes . We came home reeking of cigarette smoke and I had to put my clothes in a separate bag in my suitcase ! I swear , even the sandals I was wearing still smell like smoke .

Why did they put their clothes into a separate bag ?
Since everyone smoked , all the items in the suitcase reeked of smoke , including their sandals .
