Some dolls get diseases. Their plastic parts and iron parts change chemically and they start to cry brown tears. They are infectious; other dolls will catch it. It is air borne and can wreck a whole cabinet. You must wash them, dry them completely and keep them separated. If not, you will find all the dolls leaking brown vinegar tears, fat with rot and pent up feminine energy. It is like this with women sometimes too. We leak our iron and cry a lot. If, when you are six, you sew a piece of your hair into the seam of your doll's dress, she will reveal your real secrets to you when you are older. Then you can cry together when you and your doll are quarantined.
