The Marshmallow Caper

I built a road system last weekend so my grandsons could haul 10,000 marshmallows. I had to keep busy building the road to keep ahead of the boy’s progress so I missed the opportunity to ask where he was hauling them. I thought of so many questions later, after I was back at my home. None of them really matter, but I should have also asked what size of marshmallows they were hauling. Nowadays, there are so many choices.
When I was young, you could get jumbo and miniature. You had to buy a box of cereal to get the crunchy, dehydrated marshmallows. Nowadays, you can also get giant size and big square marshmallows intended for s’mores. At Christmas, you can get about the same size as the jumbo marshmallows but in star and Christmas tree shapes. Other holidays are starting to get their own marshmallow shapes. 
Anyhow, this set of questions brought another question to mind. How many marshmallows could be hauled in the little vehicles that fit in a four-year-old’s hand? The problem is, you can’t approach this question literally. The child has a very active imagination so it’s hard to tell if he would be thinking literally or imagining that the semi was full size. 
Another issue: I don’t think he counts much past 20 yet, so how strict is he going to be on the count? Or will it even matter? Besides that, his little brother also wants to haul 10,000 marshmallows. Will the older brother be in charge of that loading job too? I’m just glad that I wasn’t asked to load the marshmallows. Which brings to mind yet another question: Are the marshmallows loose or in bags? I don’t bother to ask. I just have to build the road and since the road just goes in a figure eight (if I can find the right curve shaped pieces), it doesn’t matter if I know where they are delivering their freight.
The little brother is two and he will stick with a task longer than you’d think, but I’m not sure he’ll stick with it long enough to get where big brother wants him to go. If big brother can decide where to go. It’s a bit of a sticky situation, especially if it rains and the marshmallows get wet. I don’t know if the trailers are enclosed or have coverings or are open to the air. My grandson isn’t worried about it, so I won’t be either. Besides, he probably controls the weather, too.
I love playing with my grandchildren. My imagination is not crusty, dusty, or out of use. In fact, I have an easier time imagining a semi hauling 10,000 marshmallows than getting up off the floor after building the road they are hauling on. At least no one but the kids are watching me get upright again. And as soon as I’m up, I sit down on a chair and stretch out my legs. 
“Come here, Grandma, and watch me unload the marshmallows,” says the bigger brother. 
“Here,” says the little brother, pointing to a spot on the floor.
I answer, “I can see you from here. Grandma has good eyes.” Which is true, as long as I’m wearing my glasses.
Somehow, the marshmallows got unloaded before suppertime and we even had time to run the fire trucks and put out some fires in the living room. While the big brother was putting out fires, the little brother started farming around the sofa. He was apparently getting good yields, considering how often he had to unload.
Luckily, I can sit on the sofa while these activities are going on. Thank goodness for small favors.
