Okay, so please if u know French answer this.

I'm actually learning French, and our teacher just gave us a vraag which is a little bit hard to me, it's about "Le style direct et indirect" (direct and indirect - in English). Here is the question:


-Sami dit à son ami "Bonjour" <=== This phrase is direct, I need it to be indirect.



P.s. I thought about asking this vraag at the 'Learning French' spot, but then I found out that there ain't many people to check my question, and it might take a long time to find an answer, so that's why I asked it here. If u just know French please help me.
