My guess is someone really raked Mr.HP over the coals for forgetting something they said and it is such a sticking point for him that he denied forgetting (or not hearing in the first place) anything you say.
Does he fill in the blanks when he is not sure what you mean?
I don't mind the sun sometime
The images it shows
I can taste you on my lips
And smell you in my clothes
Cinnamon and Sugar
And softly spoken lies
You never know just how you look
Through someone elses eyes
