末梢

末 = 一 + 木 : Mahatma Gandhi set up a giant flute on a Christmas tree, trying to raise awareness for the Roof of the World in the observatory's bathroom. He chose the flute and the tree as symbols for the sky and nature, but as Jehovah’s Witness enters, she thinks it's the sky that has fallen down on our heads, and the end of days is ultimately there.

梢 = 木 + 肖 : Sherlock Holmes (sh) set up a Christmas Tree (木) in front of the aorta (ao1). Because he lacks a star for the top of the tree (梢) he asks the little prince (肖) to chip in and climb to the top of the tree.
