SIDEWALK ETIQUETTE

I live in the beautiful and historic neighborhood of San Telmo where the streets are cobblestone and the sidewalks narrow.
And by narrow, I mean NARROW.
And since the vast majority of people who walk on these sidewalks have never heard of the sidewalk etiquette, I am going to post a few highlights:
1) When in a group of 3 or more and stopped for whatever reason, please step aside from the middle of the sidewalk to allow others to pass by without themselves having to step into the street (as residents know, this is EXTREMELY dangerous to do with the buses from hell and the motorcycle mafia sharing the roads)
2) Pregnant, elderly, and disabled people should have the right of way.
3) When smoking on the sidewalk, it is not nice to flick your lit cigarette butt at passerbys.
4) When walking your dog, please carry a plastic baggy to pick up your dog's poo from the center of the sidewalk.
5) If walking with a friend(s), it is courteous to step aside and pause your conversation for a moment to allow others to also pass on the sidewalk.
6) If you like to walk with wide steps and arms spread out, please refrain from doing so if passing someone else.
7) Do NOT litter!! This just makes an already dirty city even dirtier!!
