4get....let me explain something simply to you. Imagine this:
Lovely day, sun shining and you sit outside having a drink and along come two or three people and sit at the next table. All of them light up their cigarettes and the light breeze blows the foul smelling smoke across to your table and all over your clothes. Antisocial foul smelling habit. Just go into a house of smokers and smell the furniture, curtains and she the ash trays full of dog ends and ash on the tables.
Got the picture?
