I know a girl that craves new friends, but gets super stressed in many social situations. Her family started her on a new social skills program. She will watch and observe people. If she sees someone she finds interesting, she has a little line that she says that says she's autistic, but loves to hang out with people. She has been lucky and has met a few awesome friends. She tags along and leaves when she feels like it. They go hang out at the beach or the park and she will often sit on the grass by herself, but closeby. She may put her ipod in for a short big if she's suffering overload. She loves going places because it's learning for her. She files it away in her brain. She considers herself a master researcher of people. She does quite well on her own most days. But others she does not and has major sensory issues. She can usually tell when she's going downhill and will make an exit. Or her BFF will also notice things and help out. She never, ever goes out without one of her trusty friends by her side.
If you enjoy people, give them a chance. If you assume the worst, that can often put off bad vibes.
