My son was downstairs getting ready for school.
Upstairs--off from my normal workday commute--I'd been quietly absorbed in my thoughts: out of sight, unknown or forgotten by all--next to the light switch for the stairs.
I heard my son tell his mom he had to go back up for his socks.
As he was reaching for the OTHER switch--downstairs--I flicked the light on. Ta da !
I'm told they looked at each other.
Then he looked back up the stairs. "Daaad ! ? "
'Tis the season, for haunting. He wasn't all convinced that was me !
