LEFT appears grave as he leans forward to explain a concept. RIGHT nods sagely and expresses his agreement. A tousle-haired STUDENT wanders through the scene, too close to be just a bystander.Wait ... STUDENT? What student? That's not part of the script!
Apparently they were the Huang Engineering Center as a backdrop, and here I was, smack dab in the middle of their shot. If I had seen them earlier, I would have avoided stepping into view of the camera. But now it was too late. I didn't want to make a big scene by stopping unnaturally or flailing my arms and apologizing -- that would probably have been even more distracting. So I drifted toward the right, veering away from the camera, and walked away at a brisk pace.
I hope they didn't have to redo the shot, lol.
