Just imagine this, OK? You're out with a select couple friends doing something -- hitting the beach, seeing a show, going out dancing -- you post videos and/or pictures to "My Story" and "Our Story" and go about your merry way.
Except, you didn't include a friend or 2 in your plans and they assume you're just having a quiet night in, then they see exactly where you are and what you're doing, and BOOM...cue the drama.
