At such times my thoughts get a little poisonous where my 'non-arty' friends are concerned. All of them love the idea of what I do but very few make the actual effort to support a show.
There's a passage in the novel Past Imperfect by Julian Fellowes, who also wrote Snobs and the screenplay for Gosford Park, that captures this beautifully: -
As if one is likely to sit down and send off three thousand postcards when a personal appearance is scheduled. Obviously, they understand this will never happen. The message is really: 'We are not sufficiently interested in what you do to be aware of it if you don't make us aware. You understand that it does not impinge on our world, so you will please forgive us in future for missing whatever you are involved in.'
