After you have been in business for a while you will learn that when a client says, "before we begin..." (sorry, we have already begun) "...may I ask a quick question?  . . ." (you just did) and then follows with a question that requires many more facts and circumstances than can be conveyed "quickly."  And that one question leads to five more questions.   Which will make you want to comment, "you sure ask a lot of questions."  I won't say that to my clients, but with other professionals I will wonder why they just don't put all their questions on the table at once.  

Hint:  Don't start out with  "I won't go into details to keep it short," but then tiptoe around the subject in your next post so that we have no idea what really happened, just that it upset you.
