Using my husband and me for an example, when one of us is going to the grocery store, the other person often adds something like “Love!” and “More love!” to the grocery shopping list.
What’s a silly thing you and your partner do?
When my ex and i would watch Star Trek Enterprise, I would start screaming like Homer Simpson having night terrors whenever the theme song would start.
He’d be laughing so hard, he could barely get to the remote to skip the intro, all the while I was fake screaming basically in his face.
