Loosely based on recent events:
I've been in this specific situation a few times in my life. I'm standing in an insanely long line at a post office, the DMV or the doctors' office, and I happen to be standing right behind a mother with a young child who is staring blankly at me the entire time. No smile, no frown, just an entirely neutral expression. It's not the kid's fault--he's probably more bored than I am and is just spacing out in my general direction. And being stuck behind a grown-up with the stares would be far more uncomfortable. But I just don't have a knack with children.
