Can It Be My Birthday Every Day?

So yesterday was my 30th birthday. The big three-oh. Sex and the City and Cosmo says it's a big deal. I made it a big deal. I got all up in my head about diet and exercise and whether I had sun spots or wrinkles. I noticed grooves by my eyes when I smiled, and I tried to not make the concentration face so I wouldn't get that groove between my eyebrows. I started noticing babies more: mostly that I didn't have one. At thirty, my mother was pregnant with me: I was born a few months after she turned 31. My older sister was also pregnant at 30.
I felt like I was behind. Shouldn't I have the grownup job by now? Shouldn't grocery shopping feel like a chore, and not like I'm playing house? Should I still be surprised by adult things, like W-2s and jury summonses?
But after five months of "I'm turning thirty I'm turning thirty OMGS I'm turning 30"
(because it wasn't quite real until new year's)
I had quite possibly the best birthday ever.
Third best was probably the renaissance faire when I was in high school. All those hormones and men dressed in leather.
Second best was rock climbing a few years ago. It was my first time going, I got to learn a new physical skill I wasn't awful at, and I got to sweat and then drink margaritas. (Margaritas taste best after a sweaty day)
Best birthday ever: this weekend.
I accomplished something. I built a project, it was my idea and I was mostly in charge. My girlfriend and my husband were super enthusiastic about it, but we didn't have perfect communication. But we bettered that communication and negotiated until we were happy with the result.

Let me tell you a poly secret: there is no such thing as perfect communication. If you think someone understands you completely you're probably wrong. This happens when everything is flying along perfectly and it seems like everyone is on the same page, but sooner rather than later you will realize that your perfect system is comprised of imperfect people, and sometimes they're tired, hangry, or don't share your vision.
So you have the fights.
"But it makes more sense to do it this way"

When the actual conversation is:
I want to help you make this better. And I love you.
