As she surfaced, she realized just how much she was enjoying this spontaneous moment. She was starting to think she was happy she forgot her bag because she was having much more fun just swimming in her clothes. So much fun, she didn't want to get out of the pool. She held on to the edge for a bit occasionally dunking herself underwater again, simply enjoying the cool water. Eventually she realized, she needed to get out. She only had a little bit of time before she had to get going and she needed to sit in the sun for a bit to try and dry off. She turned and started wading towards the shallow water so she could climb out of the pool.
