"Mom, can you lick your own tongue?"
Joanne asked me that as she rolled her tongue around in her mouth. I had to think about it. I don't know, can you lick your own tongue?
And is she really asking about the capacity of the human tongue or could she be probing the boundaries of the word "lick"? I don't know, but I'm completely fascinated that she could even conceive the thought.
After some consideration, I've decided, no, you can't lick your own tongue--like the mirrors in the celestial room where you can't see yourself in the repeating reflection, only the repeated reflection of the person standing next to you--only someone else can lick your tongue, linguistically or otherwise.
Ew. That was gross.
