I am missing my little Pony tonight. He is spending the night with his grandma. No clip-clop of his little big feet. Unless I hear them in his room around 2:00 a.m. That happens frequently, but I tell myself that he got up for the bathroom, and it's his actual footsteps. That reasoning doesn't fly when The Pony is 10 miles away from the Mansion.
#1 spent the night with Grandma a couple of weeks ago. Same thing. I heard him walking in the kitchen after midnight. Except he wasn't home. You don't consciously acknowledge these routine steppings and clompings until the stepper and the clomper are not in the house!
There has to be a reasonable explanation. I just haven't found it yet.
