enviroian

I was in 1A lat night CLT-DFW on a 321. I chose a window seat because I love to look out the window. Anyway, I went to the bathroom and 3 minutes later when I return I see my window shade shut. Apparently my seatmate didn't like the glare on his ipad. I fired that shade right up and looked at him and said "really?". He shrugged and uncomfortably returned watching his movie. Has this ever happened to anyone?

Also upon boarding he pushed past me saying "excuse me, excuse me". I didn't bother to tell him we are all in the same line but just smiled when I sat next to him.
