I'm one of those that hates to be the one that always, and I mean always, has to move way over to the right to allow large groups of shoulder to shoulder people pass, coming from the opposite direction. If you overhear a woman saying, sometimes very loudly, stay to the right people, stay to the right...it's probably me.
Yes, I 'get' that it can be cultural...but, after getting a disapproving look from one man, with a somewhat snappy 'excuse me', on an escalator in London...yep, I moved way over to the side. I found out later it was considered rude to stand to the left on an escalator there....if you aren't actually walking up, or down, that escalator, you should be standing to the far right. So, I kind of expect those from abroad to figure out what it culturally acceptable here. Seriously....do we think it's okay for a foreigner to drive on the opposite side of the roads here because that's what they're used to in their country? I think not.
But in all reality? It's just rude Americans that feel they need to be able to walk right down the center of a sidewalk, strollers side by side. I tend to start to feel invisible after a day or so in the parks. I have refused to move off to the side of the sidewalk in order to allow such a group to pass by. And after they smash me in the shoulder, I hear "can you believe how rude people are? Can't they see we're walking here?' Sure I can see you...but I fail to understand why your family gets to have 9/10 of the walkway, while I stand along the side waiting for you all to pass!
Then there are the families on the buses!!! When the bus is filling up, mom and the kids tend to board the bus while dad folds up the stroller. When he boards, where does he go? To stand right in front of his particular family. Doesn't matter that no one can now get past him and the gigantic stroller. Heaven forbid he move to the back door area, where there is much more room for that stroller. When the driver yells to keep moving back, dad just stands there. Another guest asks him, politely, to move so they can pass. His answer? 'I need to stay with my group'! So now.....although there is room for about 15 more people on that bus, no one can get on because dad has prevented anyone from moving. And those with strollers just can't seem to understand why some groan when they see the stroller family coming!!!
