I'm sure the fact that we slowed down a bit did have an impact on how I perceive other's behaviour. But I am sure that we didn't encounter this many rude guests when we first started visiting. I don't have any problem with anyone rushing. I, myself, have a hard time walking slowly. But I do have problems with guests being rude to others. I'm sure that the sheer increase in numbers of guests is one of the main culprits. But I think some people just don't know how to function or act in social situations. A lot of them think that they are alone in the park so they move (slowly or quickly) through the park without showing any consideration.
I remember going nonstop before and rushing here and there. I don't ever recall impeding on anyone and if I did, I would immediately say sorry or excuse me. We try to teach our children manners but sometimes when we're at Disney, I feel that using good manners only leads to being pushed or be neglected by a CM because a loud obnoxious guest needs to be dealt with first.
I try to mind my own business but when a family has a rather loud and violent argument, it wouldn't matter if I was enjoying the scenery or walking by quickly, I will notice it. Sadly, I noticed more and more of it. I do know the financial situation and family dynamics have a lot to do with it especially during this time. But I don't think the other guests should be blamed for anyone else personal situation. I really do see a lot of people who believe that because they struggled to save for their vacation, everyone else can take a "back seat".
Also, I will admit that getting older and having less patience may add to the frustration, but people's attitudes have changed over the years and "ME, ME, ME" is predominant.
