This is a stressful read. You're trying to enjoy this cute max lovey-dovey married life, but at the same time, you're watching for the seemingly inevitable point where the other shoe will drop.
But you're not sure it'll drop. Perhaps it dropped ages ago and this is well in the aftermath where there's no problems anymore, perhaps it'll drop far in the future, well after what we see.
There's a shoe. It's dangling. You're having fun but there's a shoe just hanging there and you can't stop thinking about it.
Then you realise that it doesn't matter if the shoe drops. Nasa is a man who will go beyond the stars for his wife. He'll put the shoe on and STEP THE FUCK UP.
