沾染世俗

沾 = 占 + 氵 : Someone is pouring out a bottle of water (氵) on the higher floors of the anthill, but James II of England (zh), standing on the street (an1), quickly puts up his yellow umbrella (占) so that only his umbrella is moistened (沾).

染 = 木 + 氿 : Robinson Crusoe (r) finds that there is a small mountain spring (氿) in the anthill (an3). Unfortunately it is contaminated (染) by a plastic Christmas tree (木) standing next to it. The BPA and dye from the Christmas tree leak into the water and change the creek's color (染).

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.

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.
