Weird Contemplative Mood

And so, for some strange reason, I find myself sitting here out in a mini-park of sorts located behind the College of Fine Arts building, with the three of them. They seem kinda happy together, talking and interacting, while I just feel left out, sitting here away from them and even blogging this out. There are smiles, laughter and everything else surrounding them, but all I can feel is just a sense of loneliness.

Why?
