Your phone saved every sunset this year, and not one sentence about why you stopped to look? 7 reasons to write one line a night.

You're on the bench outside the bakery, the one where the leaves land in your coffee, and your husband asks. You open your phone and start scrolling. March, a blurry dog. June, forty pictures of the same sunset. You can tell him what every single thing looked like, and not one thing you felt.

He has his answer right away: the Tuesday the power went out. Cereal by candlelight, cards with a deck that was missing the seven of hearts. And you had forgotten that whole night.

Four thousand photos is a record of what things looked like. It was never built to hold the rest: who made you laugh, what you were worried about, the thing he said on the drive home.

That part only lasts if somebody writes it down, and one sentence takes less time than the photo did.

No page to fill and no prompts to answer. Before the light goes off, you write one line about today, on anything.

The phone charges in the kitchen now, and the journal sits on the nightstand where the phone used to be. Start tonight, before you pick up your phone.

"Power went out again. He made grilled cheese on the camp stove." That's a whole entry, and it took a minute to write.

Read it a year from now and you're back in that kitchen with the candle going. A photo of the stove would never do that.

Some nights you'll forget. The Momento has no dates printed in it, so there's no empty square waiting to tell you that you missed a Thursday.

You open to the next blank page and write tonight's line. Nothing to catch up on.

Inside there's a clear zip pocket for the things worth keeping: the ticket from the movie you walked out of, a note he left on the counter, a photo from the fridge.

When the pages run out, the insert slides out of the cover and a new one slides in, so it's the same book on your nightstand next year, full of answers.

Every Momento arrives with the cover, two paper inserts of about 76 pages each (one lined, one blank), a zipper organizer insert, a linen travel bag and a free charm that clips onto the cord. The clip, pen and extra charms you see in the video are not in the box.

The Pocket is 4.25 x 6.89 inches and the Classic is 4.72 x 7.87 inches; most people choose the Classic. A6 inserts fit the Classic; A5 and B6 are too big for either size. Refills start at $12. Right now the Momento is 50% off, with easy 100-day returns.
