Sorry for the stupidly specific question. This is definitely not something that just happened to me… Anyway…
So what do you do in a situation like this? Do you walk slower to avoid any interaction? Reach them and greet them? And if so what do you do afterwards? Just walk together? lol
Attempt to avoid, fail to avoid, blurt out “heyhowareyouyeahgoodthankshowareyou”, walk away and think about that interaction for the rest of the day.
This with maybe an additional stumble and laugh like a maniac.
