I will often say "Hai" to waiters in restaurants or cashiers at fast food places. It's especially funny when I go to Mexican restaurants where the waiters speak Spanish as their first language. They are probably thinking that they should know what I'm saying, but can't figure out why they don't. It helps though that I always nod my head yes as I'm saying it, so they at least have the body language.
Another one for me is whenever I visit a doctor and they ask me to take a deep breath... They then have to reiterate "Ok, not THAT deep." LOL.
Even though it happens nearly every time, I don't think about it I just start breathing in as I would during deep breathing exercises....
I'm also guilty of the following:
You bow entering your home or workplace...(only occasionally).
Every grassy lawn or plush carpet looks like a place to practice your forward rolls, (It's so tempting, though I feel the same way with big newly paved empty car parks.).
You sleep with your bokken beside you, or anywhere near your reach, (You never know when the invisible ninja will attack!
You watch the new Star Wars movie a couple of times so you can keep track of the sword work, then you pay attention to the story. mwahahahahaha, (I use playback and slow motion as well, especially in scenes when I think the work is dodgy or when split sequences don't seem to line up: "Hey he wasn't in that stance!").
You practice rowing exercise while using vacuum cleaner, (Since our handle is a bit short, it's a lot better on my back as well).
You open doors by extending through the edge of your hand, and moving from your centre, (I constantly do this at public restrooms).
When watching action films, you critique their fighting form.
You practice your footwork and evasion when in a crowd. And people look at you funny, (I usually do so very subtly. So if people notice, I don't notice it.)
You sometimes wonder if you could ukemi over a car if surprised, (hopfully I'll never find out, I've also wondered if I could somehow manage to do a Tenkan in water out of a sharks path LOL).
You can recite your Aikido Lineage, but can't remember your own phone number
You decide not to transfer to another university because you don't want to leave your dojo
You only take Aikido vacations, (or want to make sure hit a Dojo during the vacation).
You dream about traveling all around the world and doing Aikido in all places.
The first thing you want to know when attending your uncle's wedding cross-country is "Where's the dojo where I can get some practice?" even though you will only be out of town for a day and a half.
You purchase shoes/sandals/boots/etc based on well you could perform technique in the street while wearing them. (And shirts and pants...)
You slide forward though doors after people and turn your hips to see if you can get through the door before it closes without touching it..... (I use to do this in high school, but not so much anymore).
