i anticipated we'd be out walking in the woods this glorious fall weekend, so i took an acorn from the fidget bowl, drew a tiny face on it, and placed it along the path on an isolated bed of moss where i was sure the little girl would find it. and find it she did. she let out a gasp of disbelief, a whoop of joy, and gave me a big hug after i finally admitted that, yes, i had put it there. then she ran back to the house laughing and whooping some more and yelling, "this is hysterical!"
what a great reaction. i must do this for her more often!
