閑心

闲 = 木 + 门 : In her free time (闲) Marie Curie (xi) likes to sit in the anthill's kitchen (an2) to watch her trap door (门). She installed it right under a Christmas tree (木) so whenever someone puts a present under the Christmas tree, shortly afterwards it will fall through the trap door in Marie's secret chamber.

心 = 乚 + 丶 : Marie Curie (xi) uses a shovel (乚) to dig a hole in front of the encampment ((e)n1). She wants to bury her heart (心). To the side are three petal leaves (丶), with which she wants to cover it afterwards.
