Sometimes, I see the same person complaining about the same thing over and over again on fb. And so, I ask her nicely if I can contact her privately cos i do have something that might be able to help her with wateva she is complaining about. This is so that i dont have to ask her or comment about something that might cause her any form of embarassment on a public thread. But then, people dont acknowledge also. At least say la not now, later, not free, got meeting, or ying chau a bit la if dowan me to contact. I can see that her answering other people on that thread, just ignoring me. U think one fine day when this person come ask me a question, I still entertain her meh?
