Wading (image story in the description)

She wandered into the backyard away from the rest of the group for a quiet spot to answer the phone. She couldn't believe they were calling her. Not only was it her day off it was after hours! She snuck around the corner answered the call then realized she was looking at the back yard pool. It looked so inviting. She went over the edge and bent down to feel the water. So warm. It was cool for a late summer evening but a swim would still feel great. Without hesitating, she layed her phone on a chair by the pool and stepped in. She didn't bother with rolling up her jeans or taking off her boots. She waded around on the underwater bench along the side of the pool before she wondered if anyone was missing her from the group. She really wanted to stay by the pool and wanted to go in further. She stood on the bench and consider stepping off into the deeper water. What should she do she wondered...
