Comment jibberish

I have my blog set so that people who comment must pass the prove they are human and not spam test. However, I find it weird that I have to pass it to comment on my own blog. I understand why I would have to sign in, but I don't get why I would have to pass the human test. It is me. It is my blog. Of course I am human. The info is alredy connected to them through my computer. Seriously? All right whatever. Need to be productive today. Probably going to apply to teach some theatre to kiddies today. We'll see how that goes.
