can you tell when you pass?

lately i feel like i’ve been able to tell more and more when i pass, just how a person looks at me/interacts w me? maybe that’s just me projecting lol but for me, it’s pretty obvious w guys cuz i’ll get the lil bro nod or a “hey man” but i swear girls look at you differently when i pass. iiiiiidk maybe it’s made up and it’s all placebo since i’m probably more confident in myself, just wondered if anyone else felt this too
