During those days, I have been sent lots of business letter with different forms.  Until now, one customer  gave me a reply. I was so happy about the email, even though he just gave me his Skype. I really thought it a good beginning. And then I added him but without proved, so I sent a email to him again. What made me crazy was that he said "we have not any requirement of it".  But in the email I sent to him, I had asked two question, one is that did u see and add my skype, the other one is that would u show me which kind of the products u're interest in.  As for his no any requirement, I have no idea about which one he had answered, maybe the first, or the latter, or the both of them. 

  One is even worse . she showed her interest in our products, and told me that "should we talk later", at last, she disappeared suddenly.  But today she has shown up, is the right time for me to trouble her?
