No, you're not. Almost all my theatregoing is based around wanting to see people whose work I've enjoyed in the past or who I think show particular promise. The last time I saw something because of the production itself rather than the people involved was Love Song in January. Before that it was 5/11 (August 2005) and The Shaughraun (July 2005). So it's perhaps once in every fifty to a hundred shows I won't be wanting to see specific people.
However, the difference between me and most people is that I accept that sometimes life doesn't work out quite how I hope, and I don't go around believing that the law gives me a legal right to have everything turn out perfectly. If someone takes four weeks holiday and one week sick leave a year I have a 10% chance of missing them. That's just the way things are.
