My son has been home since Sunday. He leaves again tomorrow, headed back to college. I had forgotten the simple pleasure of just seeing him around, even if he's too busy with his friends to sit and shoot the breeze much with his parents. It's just nice to see him coming and going, fully engaged in his life. Mostly, he seems happy. That's all we ever want for them, isn't it? Everything we desire for them is in service of happy, even the challenging times that help them appreciate what's good.
