something is missing

We'd just finished dinner at a fancy restaurant and I could have sworn she was having a good time. Then, on the way to the car, she said, "I feel like something's missing." She'd even just finished laughing at one of my stupid jokes.

I took her by the hands and said, "It's okay. I'm here." I was concerned. She wasn't usually given to existential angst. "Everything will be okay." I tried to give her a big smile, though it was probably tinged with the worry I felt. I just wanted to be comforting. I wanted to make everything okay for her, even if just for a little while.

She gave me a look, then said, "No, you jackass, I think I forgot my wallet. Can we go back?"

Suffice it to say I felt kind of stupid.
