In the last couple of weeks I have flown the Alaska Boeing 737s twice sitting on a window seat on rows either 16 or 17 (the emergency exit rows).

The last two times, by the time I boarded, the passengers on the aisle and middle seats were already there.
When I pointed out that I had the window seat, they just attempted to sit back as close to their seat as possible, but did not get up or asked me if I needed them to, while also avoiding all eye contact. I found this weird... is it just me?

I am a 6'1, 185 lbs guy, not precisely small. I have trouble to access seats 16A / 16F or 17A / 17F if the middle and aisle seat passengers on my row are sitting unless I hang (aka shake) from the seat of the person sitting ahead of me (which I hate doing), or unless I awkwardly straddle facing the passenger that won't stand up.

I recently flew the same plane cross-country, but this time I was the one sitting on a middle seat 17E. The two times my window neighbor wanted to go to the restroom it didn't even occur to me not to stand up to let him in and out.

Thoughts?
