Everyone knows there are certain places where a cell phone should not be used. If your cell phone rings while you are eating dinner with guests, then it is incredibly rude to answer it. (The rudeness level jumps tenfold if you are eating dinner with only one other person.)
When you are being intimate with your partner (a.k.a. sexy time) it is also understood that if your cell phone happens to ring, then you should just let it go. Answering the phone could cause irreparable damage to your partner's self esteem, and it may also kill the mood.
There are more places that come to mind, but perhaps the most egregious is the restroom. Your own private bathroom is bad enough, but a public restroom is inexcusable.
Imagine my surprise when I walked into a WalMart restroom about a month ago to hear a man's voice coming out of one of the bathroom stalls. I went up to the urinal thinking that he may have been talking to me, but I in no shape, way or form was about to reply. Then I realized he was not talking to me; rather he was engaged in a conversation with someone on his cell phone. Now, I realize this is WalMart, so I can't expect too much out of the patrons that shop there, but how little respect does this guy have for the person he is talking to?
I can't even begin to imagine what was going through his head when the phone rang. "Oh, I'm sitting on the toilet in a WalMart, but I'm sure the person who is calling me won't mind if I talk to them now." At what point in his life did he give up on decency?
There is no decency in a person that chooses to answer, or god forbid, make a phone call while they are in the restroom. When his parents were going over the rules for being a courteous and polite person, he must have been napping. At some point in his life, he ceased to care about being the slightest bit presentable, and it was probably at that same time he started watching Nascar while eating entire bags of Cheetos and scratching himself. This may seem harsh, but until you actually see and hear someone answering their cell phone in the restroom, it simply defies belief.
I'm not really asking for much here. So, for the sake of everyone on this planet, please let nature's call be the only call you answer when you use the restroom.
