irritated by captcha

I really understand why websites use them. However, just because I understand, doesn't mean I have to like it. It just really takes me out and takes me a step back. Especially considering that those letters can be one thing or another. It is really hard to make some of them out. Sometimes it is rather clear and my life moves on without any fuss. However, there are times where I sit there and type in the code. Its invalid. I type in the code again. Invalid. Because if you miss one little letter, than its a pain. Of course, I'm glad that the bots are kept out, to not reek their little bot havoc. Still, there are times where I wish that my life would be a bit easier. These little letters can cause a lot of havoc and some trouble to say the very least.
