When a pretty damsel/cute guy approaches you and he/she is like ''heeeeey! Tony/Sandra!! because you look like the person.

And for you, it seems like an opportunity to get acquainted to him/her, so the question is will you go along with the flow or tell him/her ''PLEASE YOU ARE MISTAKEN, I AM NOT SANDRA/TONY. BYE BYE.. and off you go.

What would you do?

Of course its a different scenario if he/she is UGLY. I don't think anyone will tell you to reply ''hell no! I aint Tony/Sandra!!! Please excuse me.
