What does it mean to "see his shadow"?...
I don't understand the terminology around the Groundhog "seeing his shadow"...What does that mean exactly? How would you know if a groundhog seen his shadow or not? Do they ask him? And what if his shadow is facing east but he's looking west...but glanced east quickly at one point...how do u know if he actually "seen" the shadow?
Or are they just saying that if a shadow is present, then the groundhog has "seen it"?
