when you're on a smaller sidewalk-ed-street (in downtown neighborhoods, perhaps?) and you randomly see a group of old classmates (joy!), please step to the side if you're going to chat. don't take up the entire sidewalk and make everyone else walk around you. it's careless. same for when you're walking in a row of friends and somebody is walking towards your group. make room for them to pass, share. and do not walk while you're smoking a cigarette. the smell of smoke is extremely unpleasant to many non-smokers, especially as it blows in the wind. especially in the morning, especially in the afternoon. please, stand off to the side. it's the polite thing to do. and to the men of new york, it is beyond disgusting when you spit on the ground. it's vile, really. it amazes me how many men in midtown (where i work) do this. it's gross enough seeing spit on the sidewalk every fifteen feet, but even more revolting to see someone in the act of it.
it's a big city. many of us live and work here. we need to keep the peace because it is not going to come without a little bit of effort. be mindful, please.
