Without fail mine is always a sneeze face. It's the height of attractiveness, the sneeze face.
You can go in and change the thumbnail, and being the completely vain person that I am, I swapped it for the least unattractive one there was. But it takes 36 hours for it to register apparently. So, for the next 36 hours... achoooo!
Do you wave to other drivers on the highway? Is it a fully fledged wave, a finger wave or snob nod?
