I had an interesting conversation with two non-practitioners when they saw the kanji for aikido. One of them said it was from the menu of the local chinese restaurant. It was a perfect que for a little joke.
I told them that it was the kanji for take away restaurant.
is a lid on a pot, so the food doesn't spill.
is the steam coming off the rice in the pot, pre-cooked and warm.
is a road, you can take the food away with you.
