Incidents which stay in memory are usually ones in which we have considerable emotional or intellectual commitment. They are ‘important’ to us for some reason. For example:
Account 8: Screened
The screen was low to the ground because of the low ceiling in the ballroom, and I had found by experiment that wherever I stood near the projector, I would obstruct the screen. Furthermore the microphones had been placed in front of the screen or a long way away from the audience at a lectern. I had to stand near the audience, leaning against a pillar and peeking out around it at the audience, talking loudly to the succession of slides I had prepared. I found myself shouting to be heard, and out of touch with my audience.
