I would imagine she would get very distressed! I smoke, mum doesn't (in fact I don't think anyone on this planet smokes any more!!). Her home is meant to be 'non smoking', but as someone who is often in need of a fag when I am in there, I am more susceptible to the smell of a newly lit one. There is definiately smoking going on in that place and I suspect that it goes on in individual rooms, not communial areas. After all, rent is paid on a room which is their home. And there is no law (yet!) to stop you smoking in your own home.
