One thing that really grinds my gears is when people walk around with their bluetooth on their ear and they aren't having a conversation. I don't know why it bugs me, but it just does. Seeing people at the health club running on a treadmill with the bluetooth in, or visiting with friends while having their bluetooth in, etc. It just really bugs me. But I often think I am alone on this. Are they really 'fashionable' to wear around even while not talking or do you guys and gals feel those people look like dorks.
