Once I was sitting on a bench under a walnut tree and a walnut fell to the pavement near me and got cracked. I thought it fell from the tree and picked it up and ate it. Suddenly a crow appeared and started screaming and flying around me. I suspect the walnut didn't drop from a tree but it was the crow who throw it to crack it open. I said sorry, but it kept cursing :(, so I quickly left.
