If you are a female and feel threatened, be firm and tell him to back off. If he doesn't respond, tell him you will scream and if that doesn't work, kick him where he lives.
Are u obsessed with yourself?
Not at all.
If you were invited to compete on Dancing with the Stars (you get paired up with a professional ballroom dancer, learn how to ballroom dance and compete against other couples) would you accept and do it?
