By Sunday night they are so tired* that I swear that when we leave for work on Monday morning, they give a doggie cheer since they will be able to sleep all day.
Right now they are both passed out on the couch beside me. Falf is hiding his face since apparently the light is too bright and Willow is snoring and twitching.
*Why are they so tired you ask? Because apparently it is some sort of dog rule that they must watch you or follow you from room to room every single minute we are home. Sleeping is not allowed when it is light out, though laying in the middle of the floor like a "dead dog" so they can watch you with one eye is apparently OK.
