I think this is a fascinating phenomenon: going to see something because it's something to be seen. Well, I've now seen the actual Joconde—from two meters away, with a few score of my best friends—but I really feel I should spend some time seeing the rest of the museum.
On the other hand, I'd never been in the building before, so I just had to see the thing. I think it's a good start from a promising young painter. I can't wait to see what else he does.
