I will make no effort to claim any sort of originality in this post, as I am positive this topic has been touched on by many other bloggers. This, however, is my own take so do with it what you will.
There are a number of places where cell phone conversations are not only inappropriate, but any persons violating the common courtesy rule should be immediately killed. There is a time and a place for a telephone conversation, none of these places are 'the place'.
When you're taking a shit, or any other toileting duties (IE: taking a piss, brushing your teeth, showering, bathing, flossing, exfoliating). I can't tell you how many times I have walked into the bathroom at work and have heard attorneys on the phone while they're popping a squat on the throne. Do you honestly think people want to hear you blowing air out of your ass while youre talking to them on the phone? What's more, is what you have to say so important that you can't wait until youre done washing your hands to have a conversation about what you want for dinner? And don't think you're fooling anyone when you say, "Hold on, I've got another call coming in"...(place phone on mute, flush, return to conversation). We got your number. You know what I like to do while I'M taking a shit and someone is talking on their cell phone??? I flush the toilet. REPEATEDLY. To let the person on the other end of the phone know that the asshole they're talking to is in the bathroom.
At a funeral. You would think this goes without saying, but I was actually at a funeral recently where not only someone's cell phone rang, but the tart actually had the audacity to answer the call. She thought she was being discrete as she said, "I can't really talk right now, I'm at a funeral. Six? Yeah, I can meet you at Chili's at 6." Have some respect for the decedents family people. Leave your cell phone in the car, or at least turn it off. At this same funeral, there were scores of other tarts text messaging through the funeral. This falls under the same category as actual phone calls as far as I'm concerned.
In a car. I've bitched and moaned about this in other blogs so I won't take too much time with it here. Before any of my IRL friends pipe up, I'll also admit that I OCCASSIONALLY break this rule too. But I don't do it while I'm trying to fix my hair while balancing a double cheese burger in my lap and holding onto a soda. If you can't stay within a lane of traffic while you're talking on a phone, or change lanes without clipping the car beside you, STAY OFF YOUR PHONE WHILE YOURE DRIVING.
When you're placing an order at any food place. Look, if you don't know what the person you're ordering for wants before you get there, don't waste the time of every person standing behind you reading off the entire menu to the person on your phone. At least have the courtesy to step back and let those of us who know what we want order before you.
At a movie theater or any type of live theater. Do you honestly think the requests at the beginning of a movie that say, "Please turn off your cell phones now" don't apply to you? I do not pay $10.50/ticket to sit and listen to you tell your friends that you're watching the new Harry Potter film and talk about how cool the special effects are and give them a play-by-play of the movie. Let them pay their own $10.50 to come watch it for themselves.
While some guy is getting ready to blow a load into any of your body openings. I know I'm not the only person who watched in horror as Paris Hilton climbed off her boyfriend's dick to answer her cell phone. If your sex partner has bored you so much that you have to answer your phone, please at least have the courtesy to fake the "O" to let him know you're done and just be done with the act entirely. Don't answer the phone and then climb back on to finish.
And finally,
any time you are have a real live conversation with a real live person that happens to be sitting in front of you, have a little respect for that person. I can't tell you how many times I've felt sorry for a person when I'm out and see the person they're with chatting non-stop on the phone. It's rude, it's disrespectful. That person has taken time out of their day to spend time with you. Not sit there and listen to you make plan B.
Here's a newsflash in case you haven't figured it out yet. If someone calls you on your cell phone, there is a little thing called a call log that will let you know who called and when. When it's appropriate you can call that person back and have as much air time with that person as you need. Do it on your own time people, not at the benefit of everyone else around you. Oh, and if you HAVE to have a phone conversation in public, remember,
IT'S A CELL PHONE, not a megaphone.
YOU DON'T HAVE TO YELL to let people know what youve got to say. 9 times out of 10 its not that important anyway.
