anyone else have had people talk to you or approach you and think your one way but the min you either open your mouth or talk in depth they realize you arent?

............like me.

happens everytime someone talks to me. not trying to boast in anyway (because it doesnt benefit me anyway) but i think my looks are what make people approach me. i mean not clothes but my appearance.......

......it either takes either me opening my mouth or talking in depth for people to get this specific expression washed over there face every.single.time just about. .... .. . . they are welcoming and then they have this blank face and while i talk they start to look at me up and down and some people they start squinting their eyes and forrowing their brows.....

and then they take off in min. all genders all ages....

im 22 so a few times people closer to my age will ask if im retarded or something equivalent.
