俗世

俗 = 亻 + 谷 : Rosa Luxemburg (亻) just arrived at the space station and in the entrance (Ø2) she sees Susan Saint Bernard (su) hanging out in her web. Rosa brought some popcorn (谷) as a present and asks Susan Saint Bernard whether she wants to watch a movie, which she does. Both of them think "when in Rome, do as the Romans do" (俗), so Rosa climbs up to Susan Saint Bernard in her web and Susan Saint Bernard eats some of Rosa's popcorn.

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.
