Apparently, there is a reason why I shouldn't leave the house on Saturdays.
Got home this afternoon to find the outside water tap on my house had burst and was spraying down the side of the house, onto the rosebush and running down the walk, onto the sidewalk. The puddles are already forming into ice.
I was gone for more than five hours. Could have happened five minutes after I left, for all I know.
Oh, and there's water in the basement, too. Thank dog that all the plastic totes are on the bottom of the piles.
I've got one hell a cleanup job to do.
