Your wife looked as if she had calmed down from her ordeal so far and you both had fallen asleep during the early evening. Your wife was even too tired that she slept through the midnight change. As soon as the clock struck midnight, another rush of mermaid DNA seeped into her body. This time, it was her hair that had transformed. Your wife's hair was already grown to the base of the neck but tonight it started growing and it stopped growing when the tip reached the upper back.
She did indeed notice when she awoke the next morning. Strands of thick hair fell across her face and she sat up to inspect what had happened. She had just had a haircut last week so it was impossible to her to find her hair a lot longer than the previous night.
At around 11am there was a call from the Doctor she saw yesterday.
"It seems that the scale you gave to us yesterday has disappeared. I am sorry but we are unable to find it. If you can let us have another scale, we can analyze it right away".
Your wife checked the area where the scale was taken. The scale was back in it's original place on her waist.
"What is happening to me?" Your wife exclaims. "OK, I need to take charge. First the Doctors, then it's time for another haircut.
