i have been working as cabin crew for many years and have seen that as flying has become such routine for many of us, that passengers take less notice of the safety demo's as much as they used to.
In an ideal world it would be great to see all watching me or the video screens, but alas thats not gonna happen. I have got past the stage of worrying if someone is watching because they are reading or writing, that is up to them.
I do take exception to people who like to continue with their loud conversations during the demo.
I would politely ask that they put their conversation on 'hold' for the few minutes the demo takes. I do this not for their concern, but for the other people around them, that may not have flown much before(if at all, there are some still out there)and do generally want to listen and see what they would have to do in the event of an emergency.
I would like to think that i am acting in the best interests of the many, rather than treating a pasenger badly.
Merry xmas and happy flying to you all.
