I discovered something in Lisbon. I was in this Irish bar full of non-Irish people. The next day I smelt smoke in my room. The pub was full of smoke. I actually only managed to drink two pints of beer before the smoke drove me out.
When I was growing up all the pubs were full of smokers. It didn't bother me much, but now I could barely stand it in a room full of smokers. I am getting soft.
