When a child pays you the ultimate compliment by asking you to color with them or play outside with them, jump at the chance. Everything else can wait. Chores will still be there after the children have gone home. The world seen through the eyes of a child is a very different one from the world that many adults see. Most days, adults do not even take in much of their surroundings, being so consumed with the busy-ness of the day.
Children are more focused on what they are doing, but enjoy it.
They do not rush from one thing to another the way that most adults do. Adults could benefit greatly from this lesson. Be patient with your step-grandchildren. Remember how much of an influence you can have on their lives. Hours and days quickly turn into lost years.
