"No, you're always the yin."

Helen, Sharon, and I had a dinner conversation that only friends of many years can have. After a bottle of wine and many updates, stories, and healthy debates about each of us (we took turns), we came to a realization. We are each the yin and the yang in our individual lives.
Clarification: Yin is Black, Yang is White. Ok so turns out you can't make tables in Blogger. Whatever, I used Paint. Here's how you read it:

X is the _____ for Y.
(i.e. Helen is the Yang for Sarah.)

Sometimes we are neither the yin or the yang, but the neutral curvy line in the middle. But turns out, according to those fools, I am always the yin. So what if I'm opinionated and expressive!! !! !

Something I realized is that we will always, in the end, do whatever the heck we want. Regardless of how much scolding the other two will do, we will still follow our own gut. But we need the debate, differences of opinions, pointing forks, muted yelling, and frustrated expressions. It's how we keep each other in check and make sure that even if we are going to make huge mistakes in our lives, at least we are prepared for the consequences. Thanks guys for not saying "I told you so" but instead cluing me into the realities of this world.

I have two remaining questions:
1) Were our lives always this interesting and ironic, or is this a product of being 20-somethings?
2) What do the dots represent in our little analogy? Maybe that we always seem to agree and disagree at the same time?
