A small courtyard enclosed by a wall of bluish-gray stone, about three feet long and two feet wide, with most of the area being grayish-black soil. Only a narrow path of blue stone was left in the middle.,It took a great deal of energy and focus to finally clean it up, but the next day when I went back to check, the black threads appeared again, and there were even more of them than before.,For the next period of time, we'll have to tighten our belts.。
