one also has to remember whether it is work or study, a sub is still serving thier dominant partner. They want you to be the best at what you do...whether it be good exam results or a promotion at work.
the key is good communication at all times.
I am currently in England and S1 is in Melbourne so we have the difficult task atm of the time differences and he also works away alot. But even so we still communicate whether it be via email or plain old text messaging. And everything we do...is for each other. He supports me in everything I do and vice versa.
But of course saying that our situation is just about to change.
Just remember you are still serving your Mistress and still making her proud.
and good luck with your exams
