互让

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.

让 = 上 + 讠 : Robinson Crusoe badly needs to use anglepod's bathroom, but currently it's under renovation. On the toilet seats there's a sign saying "上" and pointing to an advertising column, so Robinson thinks that they just want him to sit on top of the advertising column, and indeed there's a hole at the top of the column.
