Explain partial negation and then provide two sentences using partial negation?

Answer 1

I requested a receipt for my sons "Child-support" payment. From his family....My son's Fiancee's mom said she would write up receipts, for him, but I dont believe they'll work, when it comes time for his income tax filing time... Because, they are not postal money order, or legal receipts, of any type... My son believes that their love for one another, "Trust" in one another is enough of a receipt.........
