What should happen when you're in one of those seats (usually on a short haul) where you have a full window to yourself and a partial of the next one behind you ?
For example, I had one such situation where the guy behind me shut the window that overlapped our seats, yet when I reclined back, the whole 2nd window was clearly in my 'space'. I then opened it back up because I wanted some sunlight.
Any guidance or opinions on etiquette here ?
