On our walks home, Kaylee and Will always ask Mandi and me to carry their backpacks for them. We almost never agree to do so - after all, their backpacks don't weigh much, we're just as hot and tired as they are, and our hands are often already full thanks to grumpy preschoolers.
One particular afternoon, after Kaylee and Will tried to hand off their backpacks and we refused to take them, Will put his own backpack back on and took Kaylee's from her. He then carried her backpack all the way home.
They walked ahead of us and carried on a lovely conversation about who knows what. It was sweet and innocent, and simultaneously exciting and painful to watch. A six-going-on-18-year-old gentleman.
