What is it about sun and sand.. that lures every living being?
Its almost unavoidable to go drowsy on the sand. I'm sure if you do a research there'll be some chemistry to this.
There's almost always the same dog at the top of the heap, few others dig in and make themselves comfortable.
Sucha warm soft feeling to see them enjoy that moment. Especially, when you're sleep deprived.
Its silly, but I actually end up envying them.
