Look Alikes?

Has anyone ever told you that you look exactly like someone they know? Could it be because they have met you before and they are just to dumb to remember? HA that has happened to me. People come up to me telling me that I look like their friends sister or something and sometimes they come up to me and tell me I look like someone they know when i just met them for the first time like a week ago. Those people either have serious memory problems or they just don't care how dumb they seem. Either way they have problems haha have a great night:)
