(Update: I should tell you, the the compliment I'm about to tell you about is sincere, was meant kindly, and was, frankly, taken in the same vein. Any assholishness here is all mine.)
I have one of those faces. Often, when people first meet me, they tell me I look just like their sister/cousin/teacher/sex therapist. Sometimes, this is uncomfortable.
I've been told I'm almost as hot as my sister. (Flattered, I'm sure.)
I look like a librarian. (With the big black glasses, that's not too surprising.)
I look like a math teacher. (Do math teachers look different than other teachers?)
I remind a friend of Maggie Gyllenhaal.
One of these comparisons is not like the other ones.
Obviously, I was beyond flattered to be compared to an actress I admire, and then...
And then, my friend continued, "Yeah, you're both manic."
(True: The best part was when he frantically tried to backtrack: "And you're both fit! And brunette!")
