[Note: A cheesy poem for a cheesy subject.]
I left my smart-phone gladly at home.
Without a phone, I am free to roam.
It was the smart-thing gladly to do.
But now tangueras tonight are few.
The cortina plays, her face is alight
With a new text from a friend tonight:
"I wish I were dancing like you!"
Absent now are techos two.
As both are in their smart-phone dance.
I just stand here with no chance.
Tango etiquette may change over time, but as it now stands, not only in Buenos Aires but also in all the world, it is considered poor manners to be on a phone or texting at a milonga. I suggest leaving the room if you have to text your children on directions to make macaroni and cheese, and other extremely important communications like this. Men... please leave your phone in your car. If you are on-call, as I have been, put the pager or a slim phone on vibrate and in your back pocket. Just warn the woman if it is in your jacket or (not recommended) front pocket!
