Gosh, I can't believe how big of a deal this thread has become! ha ha.
I guess to me it's not really even something I have to think about, justify, or specify age/gender/condition etc.
As a young female, this is how I was raised: I look at our trips to Disney as an opportunity to sort of "swim around" in random acts of kindness. I think today we are loosing the human bonds that connect us all and obligate us all to look out for one another. Sorry, I don't think the "it takes a village to raise a child" is crap. I think the buses at Disney are just one, little place where you can do something nice for someone; to make the other person, yourself, and everyone around you feel sort of warm to know that people still care.
We all know when we can help someone out, so let's just do it~!
Oh, and P.S. I would not be insulted for a man to offer me his seat. Would I take it? Maybe, maybe not, but it would be flattering to know that sort of chivalry and character still exists for people.
