Thank you MBTA.  Due to your inefficiency last night that caused 10-15 minute delays during the rush hour commute I was able to listen to my Spanish lesson twice on my way home.  I tried to stay positive about standing at the Hynes stop for what seemed like an eternity waiting for a train that I could find space on.  Finally I squeezed onto a train and closed my eyes and got my learn on.   Once again, thank you.  I marvel at the repeated delays, inefficiency, and overall shoddiness of the service provided.  For those of you not familiar with the Green Line, it breaks down several times a week.  The reasons usually are a disabled train, track fire, fallen tree branch, train derailment, or power outage.  In the future I will try to have several Spanish lessons on my Ipod and use my time wisely while waiting for a train.
