When I was a kid I was a lot shy and felt uncomfortable pretty easily when having to deal with new people. For example, when played tennis for a bunch of months I didn't know anyone, so I was extremely quiet the whole time. I could easily tell that all the other kids were kind of like putting me down and talking some shit about me.

Now I'm 24, and so are the other kids, I changed and I cultivate zero resentment towards what happened. I recently saw them recently at a big event in my city and they still act like that. I was trying to look for their gaze just to say hi but I felt that they were still thinking that crap about me. Tbh they always acted like "they are superior" but this things bothers me a little tho and I don't know what I'm supposed to do/react.

Another example is with a classmate (2 actually) from middle school (similar story to the previous one). When I crossed roads with her while walking I was trying say hello but she just kept ignoring me, I knew that she saw me because for a brief moment she looked in my eyes and looked away immediately.
