I was friends with a girl in high school who seemed like a total sweetheart. She volunteered with kids and senior citizens, and was super sweet and friendly to everyone. However, if you really got to know her you realized she was very manipulative (to guys in particular) and used people to get what she wanted, all the while putting on this sweet facade.
Did you ever know someone like this? How did it make you feel when everyone fawned over this person when you knew the truth?
