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.
