I used to not vote, but these days I just spoil my ballot paper. I scrawl 'none of the above' across it. I started doing this because, apparently, candidates have to see spoilt ballot papers. I've never found a candidate yet worth voting for, and at least if they see the paper, then they know how I feel.
My mother moans at me, telling me that Mrs Pankhurst and her chums fought tooth and nail so that I could have a vote, and that I'm being irresponsible and ungrateful. The way I look at it, those women fought so that I could have the right to vote, and with that right comes choice.
I had the right to a university education, but that didn't make it my responsibility to get one, although now that I have one, it is my responsibility to use it to the best of my ability.
Likewise, if I vote, it is my responsibility to use my vote wisely. Since voting for the given candidates would, in my eyes, be a pretty irresponsible thing to do, then I don't. Simple as that.
