I can't find anywhere a simple answer to this use case: if I leave an Airtag in a bag, at home, and I leave for 1 week (without the bag): 1) will the tag start

I can't find anywhere a simple answer to this use case: if I leave an Airtag in a bag, at home, and I leave for 1 week (without the bag): 1) will the tag start ringing? 2) Will my next door neighbour (who has an iPhone and I can often find it in my Airplay bluetooth range) receive a notification that someone is trying to track him? 3) Is my neighbour able to make my Airtag ring when I'm at home (and maybe sleeping) ? Thanks
