@Iluviaporos - It depends on what kind of resume we're talking about here though. There are plenty of places that will find you a summer job and if you just blurt everything onto the page, they might find you the wrong one.
For example, I can speak French. But the one time I told them that at an agency, they started giving me translation jobs, which I really didn't want.
Editing to make sure that you get what you want isn't out of the question.
