I'm slow to anger in some situations....wait. Scratch that. I might get angry quickly, but I don't always express it. If or how I express that anger would depend on the situation. Someone asking me to move in front of the tapestry? I dunno, it doesn't seem worth it. Or maybe, if I was in "a mood", I would be sarcastic: move aside, make a grand sweeping gesture, say something like, "Oh please, by all means." Someone literally pushing me out of the way? Oh, HELLZ no. The New York would burst out full force in a hot second.
I mean, it's not like I've never been the one anxious for some big oaf to get out of my shot, but I don't think I have ever asked someone to move unless they were done looking at whatever and were then just dithering about on their phones, blocking everyone else's view for no good reason at all. And even then, it was a very polite, "I'm really sorry, but could I just switch places with you for a second?"
The part when he talks about the picture as proof that you were somewhere made me chuckle. My father was kind of like that, but his thought was to truly prove it, one of us had to actually be in the picture. So somewhere, there are pictures of, say, the Washington monument with a tiny blue dot at the bottom of it, which is me.
