Pebbles aren’t good enough for my little one

While Elysha ran into Starbucks for a coffee today, Clara and I waited patiently in the car. Patiently until she saw the collection of decorative boulders dotting the landscape beside the car. For reasons that I cannot comprehend, my daughter is obsessed with trying to lift rocks twice her size. She began screaming to get out of the car and “Pick up the rocks! Pick up the rocks!”

The same thing happened last week while she was picking blueberries.

Could a parent with more experience than me please explain this insanity?
