Apropos is a good word.

Apropos and as a follow-on to my previous post about Photography and people blocking shots with their hand (Oh, I'm not going to link to it, just look two inches down the page), I add this: On Thursday, Gonzo, while sitting on the other side of the pod from me as I was trying to organise something at my desk, held up his fancy schmancy digital SLR and started snapping photos without looking into the viewfinder. I, being extremely busy as well as annoyed by other things, held up my hand to block him. He then cited the blog entry, saying "Don't you hate people who do that?" This gave me pause, but in my head I can up with an answer. He was not taking photos because he found what I was doing interesting. He did not think I looked good. He was not even looking at the pictures he was taking. He was using the camera simply as a tool to annoy or provoke a reaction from me. This then gave me the right to block with my hand.
