Grandchildren with us

We were privileged to look after our grandchildren on Saturday. The two of them have grown up to be a handful. They investigate their world, talk all the time and exhibit their own ideas on when to eat, bath or go to sleep. Yet, when I watch them learn something new or when they snuggle close to me so that I can read them a story, I feel a serenity that none of my business ventures can give me.
