Leading the blind...

I have to take a shuttle from U Maryland to the College Park metro, which is nice and free. I have noticed recently that if I get on the shuttle almost immediately after my last class, two blind people are usually on the shuttle also. I have also noticed that the older guy gets along pretty well and the younger girl probably does too, but she usually has people around helping her. People often help the guy too. One time I helped the girl make her way onto the shuttle (her dog doesn't seem to help her a whole lot). Today a girl was there and helped her get on the shuttle, but then must have had something else to do and didn't get on the shuttle. A lot of times when the blind girl (her name is Olivia) gets on the shuttle, people considerately move out of the way so that she can sit right in front in the (aptly named) disabled sitting. Today everyone just kind of looked at her. So, she slowly made her way down the shuttle, feeling the seats. One girl moved out of the way, but SILENTLY, so Olivia had no way of knowing that someone was moving for her. She finally sat down next to a guy (who also didn't attempt to help her). Yes, you are right, I didn't do anything either, but I was at the back of the bus. I was getting ready to help her when she sat down. Then, people were getting off the shuttle at the metro and everyone just passed right by her. One girl stopped and admired her dog, but didn't offer to help. Now one thought I might have had was that she has probably been blind for awhile and can take care of herself, maybe would even RATHER take care of herself. But she was clearly bumbling around hoping for someone to help her out.
Anyway, I went back and helped her and we had a nice conversation on the metro ride till she went off her way.
Now, I understand fence-sitting all too well. I can see both sides of every situation quite well, and often have a tough time committing to one side. I consider this situation to be a type of fence-sitting because people weren't being rude by any means, but weren't willing to speak up and do anything to help. BUT, when a person is literally in front of you and needs help, I can't imagine that your first thought isn't to help them.
