<human>: Can you condense the text into a few key points?

I am a rising senior undergrad and I just got fired from my summer internship. This was my sixth internship, and I have never had a problem until this one.

I was terminated from my graphic design internship due to performance issues. Long story short, I was working on laying out several print documents, but copy-edits kept coming through, and I wasn't particularly focused on those as a designer. While my designs were sound, the content was highly technical and I would often miss the menial copy edits I was asked to make. My work gradually shifted, until the copy edits would be the majority of my work, in lieu of designing. This was frustrating as a designer, as making these edits was my manager's job; not mine.

While making these copy edits was not in my job description, I probably should have been more attentive to those finer details than I actually was. At my previous design positions, it was never my responsibility to make sure that the body text given to me was correct; this was the responsibility of the client. However, I think that if I took a bit more time to swallow my pride and do those copy edits, this could have been avoided.

I already have another design internship secured for the rest of the summer, and potentially a second one. So at least this summer will not be wasted.

I'm trying to assess how my termination might affect future applications to other internships/jobs after graduation. As I understand it, since this was a paid internship it would show up in a background check. On my résumé I am inclined not to list it, since that is meant to showcase my best jobs/experiences. Especially if I have other jobs for Summer 2014, I don't think it would look particularly weird to omit the job I was fired from. However, if asked, I think that it would be honest and say what I wrote above. I know that I should prepare to honestly answer the "Have you ever been terminated from a position, and if so why?" question, but I'm not sure that my explanation above is a good one.
<bot>: I was fired from my summer internship. How can I explain why I was fired without ruining my chances of getting hired again?
