You know? I always listen to the safety announcements (even though I could do it in stereo with the crew after so many sectors) - but I always put down the paper/PPL texts etc etc because it is PLAIN GOOD MANNERS to give attention to someone who is talking to you..... especially when they are not trying to sell you something, but to give you information that could one awful day save your skin....
Perhaps manners are dying out. Pity.
