I was thinking, there have been many occasions in which I heard "I don't blame you for _____.  If I were you, I would've probably done that same thing."  That sounds natural and maybe sympathetical, because you are saying, "You had to make that choice and it was a difficult decision.  You had no other way out."  However, what do the words really mean?

"I don't blame you for _____.  If i were you, I would've probably done the same thing."

If we re-write that setence, we are basically saying:

"I don't blame you for that thing I would've done if I were you."

Which basically says:

"If you did what I would've done, I will not blame you."

So basically, whatever I do is always right and will not be blamed. 

Hm, that's kind of nice, isn't it?
