I also in addition to counting stairs i count sandwich bites.

A standard sandwich is 9 bites

I'm not superstitious, but when I'm walking on sidewalks or tile floors I have tended to try to avoid cracks or lines. It's an easy but engaging puzzle to try to do it while maintaining a normal gait, like the ambulatory equivalent of Sudoku.

Then, one day, my high school geometry teacher taught us about angle bisectors and the game changed permanently. Now, in addition to visible lines, any line intersections now produce invisible bisector rays that must also be avoided. I made a picture to show where you can't step on a sidewalk. It has been decades since high school geometry and I still try to avoid bisector lines any time I'm on a suitable floor. I have never added another rule to the game since, and it wasn't til this post that I thought about how strange that is.

I love Biscoff cookies, but had never had them outside of a snack on a plane either. First time I realized they sold them at stores was when my local Costco started carrying them in giant boxes, which is a little like being Sir Gallahad the Chaste, and stumbling into the castle Anthrax.

Aldi has a pretty goof knockoff version in normal size packages if you have problems with moderation 😉

But to answer your question, a long time ago, my wife and I did the "Love you", "Love you too", "Love you.... three?" thing, and apparently got up to 5 before we decided it was silly. Many years later, "Love you five" is the normal response to "Love you".

I count stairs,

There's 15 steps on my staircase at home 105 to the top of a machine i work on. 22 at the airport

My wife knows this and I don't talk when I'm on stairs my brain is occupied by counting the steps.

I think it's very strange but I have to do it

When I become aware of my hands, I need to position them so that my fingers wouldn't interfere with each other if they were ten times their length. I think something happened to me when I watched Edward Scissorhands.

I don't know, everything I do could be silly, but it's normal to me

I blow on the top of soda cans before opening them.

When I was very young I’d ride to and from school and it took me past my grandparents. During summer I’d stop in on the way home to grab a soda and because they kept them in a shed out back they’d get dusty before getting put in the fridge. So I’d blow the dust off and make sure the top is clean, fast forward 25 years and I still do it.

When browsing through used books, I try to guess which year the book was published based on typefaces, graphics, etc. and check with the copyright date on one of the front pages. For books published after ~1960, my guess is usually good to within 4 years.

It's more of a stupid habit, but I always lock my car twice. I know pressing the button once locks every door, but I can't stop myself.

My dad's and I both occasional partake in a specific ritual that goes as follows:

1. Crack open an ice cold Coke Zero (also works with coke. And probably other colas).

Take a few sips while you either pull fresh from the garden or out of the fridge:

2. Radishes

Wash them up. You can slice, quarter or leave whole.

Get snacking.

Enjoy your fresh, slightly spicy (or really spicy depending!) radishes with your cold bubbly coke.

3. Wait.

4. Burp

5. Transcend this mortal plane, bask in the glory of the radish and coke burps that follow.

Any volume adjustment that gives a numerical value needs to end in a 0, 2, 5, or 8.

Don't ask, I couldn't explain other than those numbers make me feel better.

If my wife changes it to something other than ending with those numbers I need to change it.

A few years ago I decided I wanted to improve my hand flute skills and began consciously practicing daily. Since then, I have developed the habit of playing the hand flute automatically when my hands are not busy.

All square snacks must be flipped into the mouth. Bite edge of snack, flip it (somehow, I got no idea. that's my mouths job), chew. Repeat.

Eat chips and crackers normally. Square though? Must flip!

Pick some fresh berries from my balcony planter. Do a little happy dance while eating them.

I'm a 50+ y/o man.

While lounging, I will interlink my big toes. I honestly didn't know I did it until my wife saw it and with a look of horror asked what I was doing 😆

When I pour Pepsi into a glass I put my nose over it and feel the bubbles fizz on my nose. I’ve done this since I was about 7 years old.

I like barking and do it well enough that some dogs bark back to me. Most won't, but some also have funny reactions.

I like to grab door handles with my just my index and pinky fingers. I don't know why. I've been doing it since I was a kid. It just amuses me a little. I think I started doing it pretending to be an alien.

Biscoff and tea pair well!

Tapping the top of a beer can before opening it.
