Chestnuts

During a walk in the park, we find some chestnuts and decide to wait for them to sprout. My grandchild, recalling a past experience with a dinosaur egg, wonders if a dinosaur will emerge. He then asks how to identify a chestnut tree in winter. I explain it's tricky without leaves, but we have a sign that says 'Horse Chestnut.' He amusingly concludes that a horse will come out of the chestnut.
