I had a missive on OLD.
I think it means, "I'm not interested."
Unless she states she would love to hear from you then I would assume that she is not interested.
I like that he responded in a polite way....too many times we get nothing.
Thanks guys but
Only she knows the meaning, but no harm in fishing - try something quick back like "No problem with the delay, sorry that you have been ill, how are you doing?"
