Thoughts from the front of the back of my mind

So I've just had a Formspring question about whether I'm truly happy in my relationship (in b4 "why do you need more people then?" (link NSFW)), so I'm guessing a mono has gotten themselves all in a tither about poly, which got me thinking why it is that many mono's just don't get it.

(This was originally nerd-filtered, but that's because of how I go on to explain things, which I think would still be appreciated by people not on the Nerd list)
