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.

Maud Younger (y) practised a trick shot all day in the elevator's bathroom (e4). She's now able to throw a leaf (叶) high in the air, then quickly throw a mandarin (口) and beat the mandarin with a cross (十) like a baseball with a bat so that the mandarin rips a hole right into the leaf.
