Friends or People I went to highschool don’t interact w/me on social media

So I’ve always been a woman’s woman. Like I show love to all women no matter, race, ethnicity, shape, size , stranger, or not. I often leave comments, like pictures, and say encouraging words to women on every social media platform. Im not looking for anything in return as I do this just because. But I notice I never get the same in return like friends from highschool, folks I consider my friends hardly ever show me love or anything I can asks questions on social media and no one will answer them or interact them. I just be thinking like wow ppl really don’t interact w/me on their page…it’s so weird…. They just watch my page with no interaction. I know this isn’t important I just want to know the cause of it.
