Seeing people from high school, college, and church, and all of them asking "Are you alone?" To which I respond, rather lamely, "Yes." And then it gets all awkward.
The upside of going to the Summerfest alone?
I can take as many pictures of the same carousel and Ferris wheel as I want to without anyone getting annoyed.
Another thing about going to the Summerfest alone equipped with a camera -- I cannot move thirty feet without someone asking me to take a picture of their group.
Okay, maybe that's an exaggeration. But still.
