A request to all cell phone users (my rant for the day)

When I was a kid we would take 2 cans and tie a string to the bottom of each and then stretch the string tight and talk into the can loudly so the other person could hear. Of course, the other person could hear because we were yelling into the can. This is what comes to mind when I hear people talking loudly on a cell phone. I look for the string, afterall because they are speaking so loudly there must be a string attached.
