This brings up a good point of discussion on a cold January day. Subs - how long do you expect to wait to get a reply on a session request email? How far in advance do you normally take to make a request? Mistresses - how long do you normally take to reply to a session request email? What is the optimum time in advance for a request? How much of a difference does it make if it is someone you have already sessioned with or someone new? Of course, we are assuming it is a polite and well written request.
