Thanks for your responses. I never pressure anyone or bug anyone to like or share my stuff. Ive also never sent out requests to follow me etc. I did explain a while ago to people close to me how the algorithm works and they know all about the things I do. The responses here have kind of given me an insight into what my friends must be thinking about simply not wanting to like or share my posts and fair enough. It still hurts when I see them regularly interact with and share another relatives posts and not mine.
