I got my hair cut last weekend. I hadn't been to this particular hair stylist before, and she was making all the typical small talk while snip-a-snipping.
Then she asked how long it'd been since my last haircut.
"A year," I said. "Oh, but a few months ago I trimmed it myself."
She abruptly stopped cutting, and gave me THE LOOK. This is similar to THE LOOK your parents might give you if you got a D on your algebra test or drove their minivan into a telephone poll. It's that what's-a-nice-girl-like-you-doing-a-thing-like-that-for look.
"I just cut it straight across," I protested.
She started snipping away again. "There aren't very many things that my clients say that shock me," she said. "But that's one of them."
