<p>Tenisghs, I agree with another poster, who said that no answer might be the answer, especially since many schools do not allow professors to return papers to students because of plagiarism issues (ie, fraternity test files, residential college paper files, etc). </p>
<p>You are not entitled to your paper back; your professor is not your secretary, and if they aren't responding, you can probably assume one of two things:
1. Professor may be on sabbatical and not even receiving your emails.
2. You did not build the kind of relationship with this professor that would allow you to ask for a favor and have it granted.</p>
<p>Learn from the experience, and move on, but don't ask favors from people who don't owe you anything and then stamp your foot when they don't comply with your wishes.</p>
