Leaving work yesterday and some guy starts yelling behind me, "bhai suno" and my brain immediately went into fight or flight because who yells like that unless there's a problem. Turned out he just wanted to thank me for helping him pick up his bike two weeks ago when it fell over, said he never got the chance to say it properly. Genuinely did not remember doing that at all, it wasn't even a big deal to me but apparently it mattered enough that he chased me down for it.
