And let me say that Vanessa asked these questions as if she already knew the answers -- she was assessing my knowledge of patterns. :)
Vanessa: "Is this a pattern? Triangle, square, triangle, square?"
Mommy: "Yes it is!
Vanessa: "Is this a pattern? Triangle, circle, circle . . . ?"
Mommy: "No, the triangle doesn't repeat." (Probably not the best answer I could've given, but it'll do for 6:30am.)
Vanessa: "Is this a pattern? Triangle, circle, circle; triangle, circle, circle?"
Mommy: "Why yes it is! Very good job, Vanessa."
