If you want to know if certain ‘friends’ and relations are still active on Facebook, then post something about a recent setback you’ve had and watch them come alive on your profile with likes and comments. You have to understand their psychology. Not every ‘friend’ on Facebook is monitoring your success so they can celebrate it. Many people are offended at your success especially when they feel they come from a better background than you. Many of them are watching out for your downfall so they can feel good about themselves while pretending to commiserate with you. Doubt me? Just try the exercise and see if you get the results I describe.
