The UPS man just stopped by, and he took a while as he had 3 packages to drop off and hadn’t really planned ahead. Zoe wandered over to the door and watched him, and when he finished she looked right at him and said, clear as day, “Thank you!”. He looked at her, surprised, and said “you’re welcome”. I asked her if she could tell him “bye” and she did. What a smartie pants!
Of course, now she’s closed herself in the front closet, but at least she’s smart enough to knock to let me know she wants to get out.
