Time went on, emancipation and revolution came to pass, but codigos remained almost unaffected. There were three levels of communication, glance, speech (or any other type of verbalization if the dancers had no common language) and dance.
Tango requires structure and flexibility, that is, codigos is a set of rules and regulations, the application of which is always connected with the ability to adapt to the situation considering all its finer points.
Nowadays we are self-sufficient, grown-up, educated, non-poor citizens. Men and women interact on a par, and to invite me to dance no one will look for my husband to get his permission. Sometimes couples don't visit milongas together, sometimes they do not dance the first and the last tandas with each other. So let's not be too demanding.
What I like about codigos (despite regular discussions about its abolishment since it's an atavism which is alien to the new reality) is that it protects my inner introvert. Yes, I'm an introvert. And, on the one hand I become terribly mad when somebody finds my style of communication too pushy, but on the other hand I don't like when someone is trying hard to get into my private space. I realize that we are all unique in each moment of time: me on this milonga and me on the next one - we are like twin sisters, kind of similar, but not identical. Do you remember the idea about three levels of communication mentioned above?
Sometimes, I imagine these levels to be like the rings of Saturn, which invisibly surround each person. The more introvert a person is, the further away the outer ring is, the more distance appears between the rings. The more similar is his temper to an extrovert and sanguine, the closer are the rings to him and to each other. However, these conditions for each one of us are not permanent. And that's okay!
