自怨自艾

自 = 丶 + 目 : Mnemonic symbol: a hand mirror, which someone uses to look at themselves.

The Eye of Providence (目) is looking at itself (自) in a handheld mirror (自) in the space station's bathroom (Ø4). It think it's indeed looking very good, since Zorro (z) attached a petal (丶) to its eye (目).

怨 = 夗 + 心 : Yu the Great (yu) had a very cold heart (心) last night in the anthill's bathroom (an4), and she blames (怨) her sleeping bag (夗).

艾 = 乂 + 艹 : Albert Einstein (Ø) cut himself, so he wanted to treat his wound with wormwood (艾) and mugwort (艾) in the airplane's bathroom (ai4). He finds that he accidentally used artificial lawn (艹) instead, and much worse, it has been used by someone else before. Quickly he uses a pair of pliers (乂) to draw out the artificial lawn again to stop (艾) getting aids (艾).
