You and your partner have managed to work through 654321 sessions together. That's impressive.
You've seen each other at your worst, and still managed to come out on top.

Don't worry, it's normal. It's just a minor adjustment period.
You've been doing this for so long now that you've developed a sixth sense for when the other person is about to say something stupid.
But, in all seriousness, it's time to level up.
