Ok, here's the thing. Yes, I grew up to be polite. But, I also grew up to be responsible for myself. Yes, you can see if a bus is filling up and if people are standing already..especially at night. It's just not a great idea to count on the kindness of others. If I had a youngster and a stroller? I would decide, before getting on that bus, if I could handle standing, with my child. Yes, someone could offer me a seat. But if I was far enough forward in the bus, that probably isn't going to happen. If a mother gets a seat, then her husband or some other family member feels they must then stand right there, with her. Now, the aisle is blocked. I have seen little old ladies, standing in the very front of the bus, while there were empty seats further back..but no one could see them!! I have actually taken an older gentleman to the rear of the bus so he could sit down....and it wasn't easy getting past those that 'had' to stand with their seated family members!!! I will try to find a seat for someone if at all possible. It's almost as if I've taken on the role of bus monitor!!! Yes, I take it very seriously....sometimes probably to the point of obnoxiousness. And I apologize for those that I may have annoyed. But, I will continue trying to get those that need a seat into a seat if there are any that are empty. I stop at asking people to give up a seat though. I have no idea why someone is seated..not my business. If that 35 y/o, very able looking young man wants to stay seated, while an elderly woman sways while standing? His business. He may be a jerk, he may have an inner ear issue or a leg issue that isn't visable. So, not going there.
