(I'm just putting in my two cents...from a non-greek p.o.v)
All this time that you have on your hands to bash your line sisters, can be used wisely. Instead of saying how they are lazy, trifling, don't know info, etc., why not bring them up to par. Make sure they know the information that you know.
Also, you see the way you are talking about them...what makes you think that they like YOU?
Later,
