亻 = 丿 + 丨 : Mnemonic symbol: Rosa Luxemburg. She's quite radical, and her name starts with "r", just like "ren2". Also, 亻appears at the left-hand side of characters, and Rosa is a leftist as well.

Robinson Crusoe (r) and Rosa Luxemburg (亻) are having their favorite snacks in the encampment's kitchen: Rosa is eating a banana (丿) and Robinson is eating a dinosaur bone (丨).

尔 = ⺈ + 小 : Mnemonic symbol derived from the components: a peace dove. Albert Einstein (Ø) wants to send a message of peace to earth from the space station's living room (Ø3). He wanted to give a dove (尔) a daisy (小) so that it can bring it to earth, but the dove is late! Albert has no choice but to give it to a passing crane (⺈) instead. Thus, the crane flies to earth with the daisy in his beak, just like a peace dove.
