I awake at 2 am needing to go to the bathroom. The dogs are in a deep sleep around me, evidenced by their loud snoring. I gently extricate myself from the sheets, blankets and dogs, so as not to disturb them. I ease myself up from the mattress, letting sleeping dogs lie. Tiptoeing across the floor, I listen carefully verifying that they remain in their sweet canine slumber uninterrupted. I continue about my business. I’m gone no more than two minutes, tops. When I return, the dogs, still snoring, have soundlessly moved in to MY recently vacated spot on the bed.
How do they do that?
