To the degree we can’t say no, we are not free. Here are some examples:
Can I say no to a drink?
Can I say no to a night out with friends?
Can I say no to taking advantage of another.
Can I say no to a supervisor if I think the request is unjust or unfair?
Can I say no to unleashing my anger?
Can I say no to eating what is bad for my health?
No is a powerful word when we use it to express our freedom.
