Why Do People Post Cliffhanger Facebook Statuses?

Why do people post cryptic Facebook statuses? Either share or don't share. Nobody has the time or energy to dedicate to asking you a million questions about your status that leaves people hanging. If you're in the ER, say why (seriously though if you are in the ER, how are you facebooking?). If you are going on the trip you've always dreamed of, say where (seriously though if you are leaving your home to go on yet another trip, don't advertise that your home is left unattended). People that do this are just fishing for a response. So next time you want to leave a cryptic (cliffhanger) post on Facebook, do us all a favor and don't share!
