I would guess that those people ignoring you probably didn’t mean it out of rudeness but rather they are of the same people who wouldn’t socialize with opposite gender and then go extreme by not having any contact at all ie greeting… (with) those of opposite gender (as a “geder” kinda thing)
Well, could be it appears rude and weird but they see it as like totally “lshem shmayim” (cmon benefit of the doubt… will ya’)
in that case those who cross the street are actually telling you, you do exist and therefor they’re avoiding you. 😉
