Uno
I make time for something called “uno time”.
“Uno time” is different to just time alone. “Uno” here is a shortened version of the word ‘unobligated’.
Sometimes even when we’re alone, we’re still obligated to be ready to converse with others, simply because they are in the vicinity and might talk at any time. Or we are obligated to follow the road rules or make small talk. So that’s not ‘uno’.
Being totally unobligated to others provides another level of freedom for thinking. Real “Uno Time” means you can wander free in your thoughts without being ready to be interrupted.
