Dear Jack,

Perhaps to was not fair to checkout your drawing site.
I am a professional illustrator, thinking of doing a drawing &amp; design 
Instruction site, and wanted to see your presentation.
(Which I think is well done)

But since I am not a potential student of your course,
it would be unproductive to continue sending me emails.
I hope I have not offended you.
If so, I apologize.

Sincerely, Charles Snyder
