Hi, I have a couple of questions about the usage and meaning of "wise".<br/><br/>1. When you say "John is wise to avoid it.", you mean which of the followings?<br/><br/> a.) John has avoided it already, and thus he is wise.<br/><br/> b.) John is wise enough and thus would avoid it whenever.<br/><br/>2. How about when you say "It is wise of John to avoid it."?<br/><br/>3. Lastly, when you use "for" instead of "of"--it will be "It is wise for John to avoid it."--what is the difference in meaning?<br/><br/>Thank you in advance.<br/><br/>handtalk.
