How many girls here would really care if their zipper was down?

I've had these pair of jeans for a long time and they've become my favorite! But recently they've been unzipping by themselves. I already know why: whenever I sit down the zipper lock undoes itself and it gradually falls down the more I walk. And I can't just stop sitting down! And having to zip them up constantly has gotten annoying. So I just leave them unzipped right now. I don't really care either. And I DON'T want to pay to get them fixed. It's such a rip off. But ignor all of this and just stick to my overall question.
