I don't mean to scare anyone, but I'm pretty sure that that's the Ring girl behind this young lady. You'd think that a ghost-murderer would wait until after its victim was done taking picture before it killed them, but that doesn't seem to be the case here. The Ring girl must have died before selfies and vanity became a big thing in our culture. Actually, that has to be true. That girl died back in the days of the VHS tape.
The best we can hope for this young lady is that that's not the Ring girl behind yet. Instead it might just be her sister. In that case, the sister is going to get a whooping for ruining the selfie. "GET OUT OF MY PICTURES. NO ONE WANTS TO SEE YOUR GHOST-LOOKING SELF BEHIND ME!"
