i saw someone i knew in passing. the rule is if you're on your personal device you are not beholden to engage outside, or if you are pretending the dog (unless the dog calls attention to you), or if your peripheral vision is blind, or if you do not pass within a certain distance, or if in this case you are on the other side, and on a mundane mission, you are not obliged. i looked at the dogs. i thought, i'm not really on the map, (though i have sometimes tried). i just cross paths. unless until unless maybe something happens or someone tries, i'm just a passerby.
