“Should you be drinking coffee if you're about to go to bed?” Dill ignored Harold's frantic head shaking. “Only I've heart that speeding up your heart rate isn't good for a state of relaxation.”

I'm well aware of the effects of coffee on the central nervous system and I'm sure by the time my visitor leaves there will be no trace of caffeine in my system and I'll enjoy a blissful two or three hours of exhausted rest.”
Harold bent to his work in a desperate attempt to block out the mental image of his mother's sexual activity. It was probably his father she was expecting but he knew her appetites weren't always reserved for what the Lord of Hell had to offer and for his part he was generally happy that she was happy, though woe betide any demon who left her not fully satisfied.

Convinced he had the right spell he looked up and waited for a convenient moment to interject.
“...so I'll thank you to keep your opinions about the chemistry and your speculation about my sex life to your self in future.”
