I think I'm just going to submit this report for class without adding another student's name
Why aren't you gonna add his name?
I just wanted a little help from the guy.
It's wrong to take credit when someone else helped you. You should should add his name to the report.
I didn't want to work with other people, so I asked nicely if he could write it.
If wrote it by himself that makes leaving his name of even worse. He deserves credit for the work he put into the report. You should do the right thing and put his name on it.
