About to slip in (story of the image in the description)

The lodge at the lake had been the breakfast stop but now were exploring outside along the lake before they went on to their next stop. She went out on the dock and sat on the edge. It was cold that morning when they left. But now it had started to warm up and she was starting to second guess the sweater. That was till she went out on the dock. As she was sitting there her friend came out to ask what she was doing. She uncrossed her legs and stuck her feet out over the water and said, "Dare me?" Before she could get an answer she dunked her feet in. She was sitting on the very edge and her jeans were now wet to her knees. Her friend exclaimed, "What are you doing!" "I'm going swimming!" she replied and slid off the dock into the lake. It was deeper than she thought, she went completely under. She swam back along the dock and waded out. Her friend exclaimed, "You're crazy! Do you have extra clothes? She looked at herself, giggled and replied, "nope!" She didn't care. She loved this!
