I Am WHO's Look-Alike?

Or more appropriately, WHO's my look-alike? One of my classmates told me yesterday that I remind him of one of his really good friends, both looks and mannerisms. After my reaction, he said, "Exactly. That's something she totally would have done too." Since I've been in Portland, a few other people have told me the same thing. I get that a LOT. Even before Portland. It's interesting. I must just have a familiar face I guess....
