互相依存

互 = 一 + 彑 : Helga Horse (hu) is freezing in the space station's bathroom (Ø4). She rubs her two front hooves mutually (互) against each other to warm up a little. Even her wet snout (彑) is frozen: she cannot play the flute (一) anymore.

相 = 木 + 目 : Mnemonic symbol: I take "eye" and "tree" as resembling an ent, an alive tree. Xi Shi (xi) portrays (相) an ent (相) in the anglepod's bathroom (ang4). Unfortunately she's really bad at painting, and her portrait resembles more a Christmas tree (木). The Eye of Providence (目) enters and, just from the shape of the Christmas Tree, instantly recognizes its own portrait (相).

依 = 亻 + 衣 : Maud Younger and Rosa Luxemburg have been stranded in front of the space station. They both depend on a single kilt to keep them warm.

存 = 一 + 仔 : Mnemonic symbol: a floppy disc. Kitty Cat (cu) wants to protest against the law that women have to wear skirts, so wearing jeans (仔) she dances and plays a flute (一) in the encampment's kitchen ((e)n2) and records her demonstration on a floppy disc (存) to upload it later to her livejournal.
