Zeph who had just arrived at his house found nothing amiss as he quickly climbed up to the roof of the house. Due to various reasons, he prefers to use the roof as the exit and entry door for his home rather than the main door which remains locked always to not let those neighbors know that anybody lived here.
Everything was normal as it should be with the right amount of dust gathered all around. He never cleaned, what a joke? Wouldn't it be a clear message to all that this house is in use after the house began to get miraculously clean on the outside?
But it also didn't mean that he lives in dirt. It was the classic case of not judging the interior from the exterior. Contrary to the dusty outside, the interior of the house was in pristine condition as Zeph lives too frugally and except sleeping in and resting he does nothing inside which could spoil the innards.
