A few weeks back my SFO>BOS RPU didn't clear, and I ended up on the two-abreast aisle side of an unrenovated 772. My seatmate in the window seat was a 1K, and I couldn't help noticing that rather than ask me to get up when she needed to use the lav, she made a point of only going when I was already out of my seat.
The first time I figured it was a coincidence, but the second time I almost felt guilty. I'm sure plenty of other window seat occupants do the same, but I was still struck by the selfless gesture. The opposite of DYKWIA.
