Derek and Andrea were discussing many important things.
Andi - "I wonder what I will look like in the future?"
Der - "Well, you will have white hair, your body will be poof, poof (indicates with his arms more space around the body), but your face will still be the same. You will look like grandma, but with your face."
Andi - "Oh yea, you're right!"
They then moved on to another subject - what plants do while they are buried under the snow.
