I took a 4 mile walk last night after midnight.

Once about ten years ago, I took a walk for a few blocks around my suburban neighborhood at about 2:30 in the morning. I figured I could enjoy the feeling of walking around a dark, totally deserted street. Until a boy of about 12 passed me on his bike and casually waved and said "Hi." I have no idea what he was doing out there (he wasn't delivering newspapers, just cycling around). Just an odd moment.
