Chatty Metro Engineer

Here's to you chatty metro engineer. You forced me to jack up my iPod almost all the way so I could listen to your cheerful droning of the rules and regs of Metro. We all know stand right, walk left on the escalator (except for tourists). We all know let everyone exit before you board. We all know use all of the doors. Was it necessary to fill all of the time, except 10-15 seconds of blissful silence, between stops with your reminders? Finally by National Airport, you ran out of gas and were only saying "Doors on the right." Next time, keep it down. I might have a conference call on the ride home.
