One of those faces

The first two weeks of school are always interesting. Between figuring out your schedule, not panicking every time you look at the syllabus and generally having a headache from having to think again, it's the most stressful time for me except finals week. The other thing that keeps those weeks interesting for me is keeping track of how many people recognize me when I've never met them before in my life.
In my very first class, latin dance, a guy sitting a few seats down waved and said, "I don't remember where I know you from."
I took one look at him and said I have no idea either. Then, my boyfriend took me to Texas Roadhouse for dinner, and the server took one look at me and thought we were regular customers.
We'd never been there before.
The strangest time, though, was when I was waiting for my luggage at the airport and a girl came up to me and told me she'd been staring at me the whole flight trying to figure out how she knew me. I had no idea who she was.
This has become such a regular occurrence I've kind of come to expect it, but I still have no clue why people think they know me. I can't think of anyone in particular that I look like, except the few people who tell me I look like Pam from the Office.
Whatever it is, it makes young children smile at me and random dogs start following me down the street. It was one of those miniature dogs, and it was outside with it's owner when it just latched onto me and followed me whichever direction I went.
Needless to say, I've been feeling a lot of love from complete strangers, human and nonhuman.
