The Code

There is a code among women, among people really regarding dating that I would like to publish here, simply because I would like more people to be aware of it. I was pretty sure it was a universally understood and followed code, although due to recent events it has come to my attention that this is in fact not the case. The code is as follows:
If your best friend breaks up with his/her boy/girlfriend the ex of your best friend is off limits! The exceptions to the code are as follows;
a) the best friend gives you express permission to be with their ex
b) you no longer care to be best friends with the best friend
c) the best friend dies
d) the best friend leaves the country and you will never see them again
These are the only exceptions to the rule, and likewise it is generally assumed that the code applies to any close friends, not just best friends.
