Do you ever get mistaken for someone else?

I am constantly having people coming up to me thinking they know me, when we've never met. This happens on an average of twice a month.  In the last year and a half, I've had 4 or 5 people ask me if I ever stayed at the women's mission. When I tell them I haven't they then say I look just like someone that either stayed there or worked there, I've heard both. I guess I must have a twin or two out there....
