No celebrities, but I get the somebody's cousin thing a lot.
My cousin's ex used to tell me all the time I looked like the girl down the street except I didn't have the lazy eye. I was like, huh?
A lot of people in high school used to say me and this other girl looked just alike. I didn't see the resemblance until graduation when we took a picture together (we were pretty good friends) When I saw the pic of us in our caps and gowns, I was amazed to see that we did favor each other.
I guess my boyfriend and I have been together for so long that people say we look alike.
