A Disappointing B+

Argh. I got my first essay back and was really disappointed with my B+. I wasn't disappointed with the grade assigned by Fr. Ruff, I did pretty much nail the topic and would have probably received an A had it not been for a number of stupid, stupid grammatical errors. Actually, I would have given myself a C. What is disappointing, and rather embarrassing, is that I regularly write, and edit, and review papers for journals. There was absolutely no reason for those mistakes.
