Friday morning in academy meeting the AP mentioned that kids are like cattle: when the weather gets bad they go crazy. Having never worked with cattle I cannot comment on the validity of this statement, but I can say that as a rather impressive storm rolled in Friday afternoon my kids went above and beyond their normal level of insanity.
My kids are usually anxious to prove any administrator wrong, so in one particularly boisterous class I mentioned the cattle comparison. Surely they would be insulted by being likened unto livestock, and anxiously prove their superior intelligence by settling down. Instead they embraced the analogy and started mooing.
