The photo below is to demonstrate that there are people in this world who have their own agenda and will follow it regardless of where they are or who they're with. This is something to fear since many people out there have made a habit out of meeting new people. While this is an exciting and worthwhile endeavor, be sure to screen your new friends carefully or you may end up with someone like the girl on the right. I'm guessing she became friends with the rest of the group, exchanged phone numbers and address, helped a couple of them move, then POW! started flashing her cans at every photo op. Now no one has the courage to tell her to get lost since she's such an awesome pet sitter and thus they are stuck with her forever.
I added the snails for decency's sake. You're welcome.
