oh my gosh. How do you know? Are you a selfie type of a person?
Good news for you. Habitual fb selfie people are Narcissist. Heard it on the radio that science have proved it.
Never took a mirroring image before, virgin at it
and FYI I don't own a FB presently, at one point I did thou but I never put up pictures. What science and who signed off on it?
