I actually left the morning BART train today feeling good, feeling that there are decent people left in this world.
In a semi-crowded train today, an elderly couple walked in. About 4 seated passengers jumped up to give them the seat. Then 2 other passengers gave up their seat to the 2 people who surrendered their seats to the elderly couple. I was standing in the back of the train, but observed this rare moment of good citizenship and community with a smile.
I walked off the train feeling positive and hopeful today. This type of consideration really doesn't happen often on BART. I'm not sure if it's because it's a sunny day (after 4 or 5 days of consecutive rain), or this train just happened to be filled with good people, but it was a pleasant display of selflessness.
