Oh! How's school Andrea? Do you have an assignment?
I have an assignment grandpa.
We are tasked to bring the most fascinating and useful invention we have ever seen.
What is it?
That is why I am here. I am to ask you, what for you is the greatest invention of all grandpa?
The greatest invention for me is the furnace my beloved. Your grand mother and I's love started in a place with a furnace.
what will you bring?
In 1885 the first riveted-steel coal furnace was built. Without electricity and fans to move air, these early furnaces transported heat by natural convection (warm heated air rising) through ducts from the basement furnace to the rooms above. That kind of a furnace symbolizes our love.
By the way, your sisters are waiting for you. They told me to tell you that you will have a movie marathon.
