浮世

浮 = 孚 + 氵 : Ever since Frieda Fox (fu) got her wedding ring (孚) just inside the space station's entrance (Ø2) she's been floating around (浮) like on clouds. She even got drunk by only drinking a bottle of water (氵).

世 = 廿 + L : Mnemonic symbol: the WTO or WHO.

Sherlock Holmes (sh) is cleaning a flower pot (廿) under the shower of the space station's bathroom (Ø4) with a loofah (L) because he didn't quite understand a poster next to the shower from the WHO (世) explaining dangers arising from different germs.

In this case, L is for loofah.
