I need a word for the people who pass by pleasantly
you see them now and then, have no beef or grit with them, nor any intimacy.
just mildly to seriously, pleased, to see a friendly face
to engage too closely with introductions is to lead to more intimate things like BBQs and hiking, even sex, which can become too much if not looking for it.
The enjoyment comes from distance and lack of baggage, a sheer pleasantness for passing by.
