People who have ear buds in their ears simply cannot hear danger approaching. All they hear is the pretend soundtrack of their lives. People walking with ear buds in cannot hear a dog dashing up behind them nor can they hear the footsteps of a thief or murderer sneaking up behind him or her either. People who drive their cars with ear buds plugged in their ears (an act that is considered a traffic violation in many states) cannot hear a child screaming or a horn blowing in warning. Cell phones are known to be a factor in many car accidents. I won’t even mention how distracting ear buds plugged into a cell phone can be for a student in a classroom setting! We basically have handed a device to students that invites them to not pay attention to the real world around them.
