Mercury In Retrograde

And so I heard someone say the other day, planet Mercury is in retrograde. And I think that means watch out for what you do and what you say as things can get wacky left and right and life can become like that karma thing of Murphy's Law, "Whatever can go wrong, will go wrong". I don't know how long mercury has been in retrograde or if what that person said is even correct, as I have not seen any of its affects in the immediate world I have been inhabiting lately. Or maybe I have seen Mercury's effects lately, I am not sure. And what does Mercury being in retrograde mean anyway? Well from what I hear, Mercury is the God of communication and war I think. Doesn't those medical staffs that fly away on the wings of love have something to do with Mercury; those snakes and that all seeing eye that sees all thing. And doesn't Mercury being in retrograde have to do with communication being out of whack? Does everything technology just stop working or go backwards. Well this computer seems to be working great so far today. And what else does Mercury in retrograde have to do with? The planet goes backward or something so everything else in life goes backwards until it decides to go forward again. What ever this retrograde thing may mean, have a great Mercury in retrograding day.
