I think the depth of adolescent lethargy can only be fully experienced in winter, trying to drag their sorry self out from under the blankets to get to school on time. My workmate had a discussion with his son about next year's high school choices. He was browsing a prospectus for a school he was keen on. 'Bus leaves at 7.25am,' his son said gravely. Then he thought for a bit. 'Dad, I think I could catch that bus,' he said optimistically. 'At least on the first day'. Charming.
