We were out for a family picnic in the park. 
My husband and I were relaxing on the grass while the kids played nearby. Suddenly, our son ran over to a tree and shouted excitedly:
— Mom, look at this beautiful tree! It has patterns all over it! 
I thought he just noticed some interesting bark and wanted to touch it… But right then, my husband jumped up in panic and ran toward our son.
The boy was already reaching for the trunk when his father got there just in time to stop him and prevent something terrible.
