Later that night I was awoken by giggling and grunting in the garden. I peeked out of my window and was surprised to find Michael and Emma carrying on by the hot tub. I tried to go back to sleep but was kept awake by much splashing, laughing and moaning. Sounded like woo hoo to me. Of course, it may all have been a dream.
In the morning, Emma wasn't there but Michael did look very pleased with himself. I said nothing.
