It turns out I was wrong on both accounts. I've been alone in my apartment, my roommates having not returned from the holiday break, for a week now. It has been a strangely enjoyable experience, despite my former reservations. I've been hiking and taking walks on the beach, reading, knitting and having an all around good time all by myself.
As my friends arrive back from their trips home and I tell them that I've already been here for a week I hear things akin to "Oh you poor thing." And I guess I just let them sympathize for me because it would be much easier, and would spare me more doubtful looks, than explaining how much fun it's been.
