therse people are rude, sacrilegious, and dangerous. talking in movies, rude.
taking in your own house if worship, sacrilegious.
talking while driving, dangerous.
one of the most convenient products made in the last few years, and a few, too many few, abuse it.
when i lived in new york, there were always characters walking around in robes or sometimes in regular street clothes, that talked to themselves. they never hurt any one, they just lived in their own world.
if i saw one of the characters now, he would probably have an earpiece and a cell phone in his pocket.
