With the rain and delays today, it was very pleasant to see someone so considerate and courteous on BART, not to me (I was just observing from afar) but to others around him. He looked like he was in his 50s. He was sitting down but immediately got up to give his seat (not a handicapped seat) to a slightly older woman who was very happy and gracious to be seated. Then, as he was standing, he noticed that another woman was struggling to reach up to the safety pole due to her height. He immediately offered to trade spaces with her so she is able to comfortably hold on to one of those handles attached to the seats.
If you're this man and are reading this, I just have to say wow, there are very very few people left in this world (well, at least the BART world) who are as considerate as you! Thank you!
