One Friday night in the dead of winter, we ran out of oil for the furnace. The oil company would not be able to deliver until after the weekend was over, so mom and dad decided thay needed to at least keep some kind of heat flowing through the house so the pipes would not freeze.
They decided to take shifts and one or the other would stay awake near the oven to make sure nothing caught on fire. Dad went first. He was sitting in the kitchen in the middle of the night reading, when he suddenly heard footsteps crunching through the snow coming up the back steps and walking up to the back door.
Dad waited a minute, wondering if a burglar was trying to get into the house. Finally, he crept to the back door, flipped on the porch light and threw open the door , ready to tackle an intruder.
Not only was the porch empty, but there were no footsteps in the snow.
Dad was quite unnerved, but this was nothing compared to the experience my mom would soon have.
