Rant: cell phones

Since living in Atlanta I have developed an intense dislike of cell phones. For the most part, they are very handy and I enjoy having one for emergency situation in which I need to contact someone and I love having one. I also understand that the land line is slowly being phased out and many people only have a cell. Which is fine, that's not was irritates me. But here is a list of reasons that do:

1) People who asnswer their cell regardless of where they are or who they are talking to. If you are expecting an important call by all means answer it. However, if you are in the middle of a conversation with me and some random person happens to call you, then fucking leave it! (This just happened a few minutes ago with a coworker, so rude).

2) People who come into the office on their phone, and expect me to figure out when they are talking to me and not the person on the phone. If you want something get off your phone and talk to me, if not don't expect me to acknowledge your presence.

3) People who yell into their phone. I don't give a shit who you saw doing what at the frat party last weekend.

4) People who talk while driving. I have answered the phone briefly while driving, but never to have a long conversation unless I'm stuck in traffic. I'm sorry, I don't care how good of a driver you think you are, but stay off your effing phone. I can't count how many times I've almost been rear-ended, cut off, or run over by some asshat on their phone.

Before you get offended, it must be said that most people we know have excellent cell phone ettiquette which I appreciate.

I just can't figure out why people need to be on the phone all the time. One of my favorites is people at the gym on their cell phones. WTF? We recently saw someone on a jog on their cell phone. Emory is the worst, I would say while driving through the campus 8 out of 10 people are on their phone.

What is this need to constantly be occupied? Is it that bad being left alone with your thoughts?
