That even if you want to be pregnant and have actively been trying to get pregnant, there will still be a moment when you look at the positive test and think "Holy SHIT! I'm pregnant!" and your knees will go weak and you'll panic a bit. That my body, which has failed me so much and so often in the past, can conceive, carry to term and nourish a child. Not effortlessly, by any stretch of the imagination, but it worked, and it is continuing to work, and this astonishes me daily.
That really good friends can be found in places you don't expect, and that people you thought were friends can disappear from your life with very little warning.
That everything washes.
That making pastry isn't as scary as it seems.
That there's a very good reason that pregnancy takes so damn long, and even then, it isn't nearly long enough to adjust to the culture shock that is being a first-time parent.
That quality really is better than quantity in almost everything.
