Noah's view of women: mad, mucousy sharks

Noah: Are you mad at me?
Me: Not at all. Why?
Noah: I don't know.  I don't understand women.  They always seem mad.


A couple minutes later, I'm teaching about sharks.
M: If a shark loses a tooth, one of the teeth from a row further back in the mouth advances to replace it, and another grows in place of that one.  The back rows of shark teeth are backup teeth.
N: Just like Sarah!

Later I'm teaching about lamprey eel larvae in biology.
M: They feed by producing strands of mucus that trap food particles floating in the water.
N: Just like Sarah!
