unit#4, past perfect (2nd round)

reported speech! 

A friend of mine said that 

he had drunk 6 days a week, 

but he had never been late for work.. 

My father told me that 

my grandfather had had clear memory sometimes, 

even though he had suffered from dementia.

One article said that 

King Crabs had been sold in half price,

but it turned out to be a kind of marketing.
