For example, consider two college roommates. One wishes to
his freedom of expression by listing to music until 3 AM in the
morning (without the benefit of headphones, of course!). The other
wishes to exercise his right to get sufficient sleep so as
to be well
rested for the big exam the following morning. Clearly, each
roommate, taken individually, is exercising a reasonable
in this case they have come into conflict.
The student listening to music need only put on headphones,
then they will both be happy. It's a poor analogy.
Need implies accepting someone elses constraints. That's a poor
simplification, because 100 people could tell someone that they "need" to
stop posting friviously and harming list progress, and they can still chose
to ignore it if there are no teeth to the rules.
