A robin sat on his hat the whole time. He never knew.

It's Theo's first winter in a little mountain town. String lights over the square, a big decorated fir, a crooked snowman outside the shop. He sits on a bench with his head down while two kids pull a wooden sled past his boots. A small round robin lands on top of his red hat and stays there. He never knows.

Then the phone goes down on his knee, a snowflake lands on the dark screen, and he looks up. You've had a robin on your hat too. Every first winter has a few.

The first year in the new house. The first winter after the kids moved out, or after you stopped going to work. It feels endless while you're in it. Then one day you can't remember what the kitchen smelled like or who you called when the pipes froze.

Nobody writes those down, because nothing happened. That's what you'll want to read later. One customer put it this way in a comment in September: "it is fun to see my life on paper at any given year."

It arrives in a linen travel bag. Inside: the premium leather cover, two 76-page inserts (one lined, one blank), a clear zipper organizer insert for the tickets and notes you want to hold onto, and the charm you choose. US shipping is free.

Not in the box: a pen, the clips, the ribbon, the stickers and the extra charms you see in the video. Grid and planner inserts are sold separately.

Seasons don't keep a schedule, and neither do you. You'll write through a snowstorm and then not again until the thaw. There are no dates printed on the lined or blank pages, so nothing shows the gap.

Open it in March and the next page is just the next page. Nobody's keeping score. It's your winter.

When the pages are used up, the insert slides out and goes on a shelf, and a fresh one slides into the same cover. Refills start at $12, about 76 pages each. The first winter gets its own insert, and the next one starts where it left off.

The lifetime warranty covers the binding, the cover and the hardware. One customer texted us in October, "Life. Nothing specific like travel just everyday." That's what goes on the shelf.

The Pocket cover is 4.25 x 6.89 in (108 x 175 mm), with pages of 90 x 163 mm. It's the one for a coat pocket. The Classic is 4.72 x 7.87 in (120 x 200 mm), with pages of 105 x 190 mm. That's the one for longer entries at the kitchen table.

Will your own inserts fit? Traveler's Notebook Passport inserts fit both sizes. A6 and Hobonichi Weeks fit the Classic only. A5 and B6 are too big for either.

The Momento is 50% off right now: the Pocket from $69 and the Classic from $89. The charm is free, US shipping is free, and you have easy 100-day returns.

You're the kind of person who wants to remember this part. Choose your size and your charm. Tonight, put the phone on your knee and write one line about what your street looked like today. Then look up. There may be a bird on you.
