On Mobile Phone

There are some circumstances where a mobile phone should not be used at all: turn the thing off or let it in silent mood for a little while. These are circumstances where the ringtone and ensuing conversation would be obtrusive, such as at a movie, concert, or church service.

There are some circumstances where using a mobile phone is fine, as long as the user thinks anyone who happens to be actually standing near them. Think of a person standing in line at the supermarket. Before s/he gets to the cash register, they may talk away. Once they get to the register, however, it's time to say 'Look, I'll call you back in a minute,' and hang up. Remember that the person standing behind the cash register is just that - a person, and should be treated as such.

As long as you don't ignore the people standing around you, and don't talk really loudly, and the conversation doesn't intrude on what you're doing, talk all you want.
