“Free time.” What a delightful expression! Does this mean that what remains of time is not “free time,” but rather time of imprisonment, constrained time, and time in a cage? Yes, undoubtedly; otherwise, we would not say “free time.” What is the difference between “free time” and “not free time”?
“Not free time” is the time filled by someone else besides us. It is any time in which someone else decides what we ought to do.
