The Boy: Mommy, you don’t have that much gray hair.  You only have 1, 2, … (he proceeds to count every single one of the gray hairs on my head) pieces of gray hair.
Me: Strands, Son.  Pieces of hair are called strands.
TB: Well, you only have _ strands of gray hair.
Me: Oh.
TB: Well, that kind of is a lot.  But you don’t have as many as Daddy.
