An idle mind

Some days all you want to do is sit down and let your mind wander....

Doing nothing, just staying there wistfully thinking or blissfully reminiscing.

Getting up whenever you wanted and not because you were in somebody's way or somebody wanted something.

Some days you don't get that....

You just have to work, get it done by the end of the day.

Those are the days which give you something to think about when all you want to do is sit down and let your mind wander.
