If I'm in the bulkhead, which I usually am when I'm not upgraded, I stow my stuff about 10 to 15 minutes after the nose dips (which is normally 30 minutes prior to touchdown). I know from experience that I must stow my bags in an overhead bin and I know that I'm going to be told to do that, so I get off my a$$ and put my carry-on stuff where it belongs and don't make a big deal out of challenging a F/A about whose responsibility it is to care for my personal belongings.

But I may be different than most as my mother weaned me at an early age!!!
