Fashion Show and Rehearsals (mvn08)

I went into Muvenation Island to watch the fashion show. I came in on time but time in SL seems to be quite different from time in RL. I sat at one of the tables and waited and waited and waited until I started multitasking. I find that I have been wasting a lot of time waiting for things to happen in SL these past few weeks. I am now wondering whether this is a trend in SL. I am interested in using SL as a tool for instruction and learning. So far, I have been patiently waiting for things to happen. My observations have led me to conclude that SL is more of a show or display of avatars that needs lots of rehearsals. Am I missing something?

I would love to hear about others' experiences.
