That's where Dan stood and held court, just weeks before the accident.
Over there by the refrigerator, that's where Bob and Susan met.
That's where the mistletoe was hung.
And that's where Anne was sitting when Whiskers came out from hiding and got right on her lap.
If you close your eyes and tune out everything else, you can almost hear the past.
