Daphne had just realized that she hadn't packed the fedora she had in mind for the snowman when her partner in crime, whom she had never met, decided to join her. With a wide grin, she turned toward him and thrust her palm out for a handshake. They hadn't properly met, at least not officially!
"Hello! I'm Daphne," she spoke with such exuberance that she practically glowed. "And I'm not cold! At least not yet."
So what if her knees got chilled? Surely there was enough clothing on the rest of her body to compensate. If they were to get completely covered in snow during the planned outdoor activity, then she would use a warming charm later. Easily done! Thank Merlin she was a witch.
