相

木

目
:
Mnemonic symbol: I take "eye" and "tree" as resembling an ent, an alive tree. Xi Shi (xi) portrays (相) an ent (相) in the anglepod's bathroom (ang4). Unfortunately she's really bad at painting, and her portrait resembles more a Christmas tree (木). The Eye of Providence (目) enters and, just from the shape of the Christmas Tree, instantly recognizes its own portrait (相).
惜

昔
:
NASA ordered Marie Curie (xi) to do an experiment for them in front of the space station (Ø1). They are spending 2000000000 bucks to see what happens when you crush a milk shake (昔) with a flail (忄) in outer space. Marie Curie thinks it is a pity (惜) and would rather drink her cherished (惜) milk shake rather than crush it.
