My friends took my work and wanted to copy it. But I told them that I haven't finish all the questions. Then after they copy, they blame me for not competing the work an pushed the responsibility to me. Wtf is this man. They wanted to copy, so stupidly. And blamed me. What should i do. Omg.

I gave my work to some of my friends yesterday for a difficult project. I told them they could copy it but it might suck. They were cool with it, why?
