Alanna is tired and she is constantly yawning. She noticed that not all yawns are the same and came up with the idea to measure her own yawns. Alanna took a ruler and every time she feels a yawn coming she takes the ruler and brings it to her lips and measures her yawn. Alanna herself is surprised at how wide she opens her mouth when she yawns.
