If eyes are the portal to one's soul, house doors must be the gateway to a life. The house connected to this door is for sale. The owners are ready to downsize. Their things have been sorted,reduced in volume. Decisions made as to what is important, what things define them.
It was a happy process. One not done from financial pressure but instead from a realization that it is time to evolve, move on to another stage of life. Find another door to be their gateway.
