Different is Not the Same!

It has become fairly obvious that my external brain is completely unhinged.  She doesn't know the difference between "different" and the "same".  She says that the knee and the neck of a person is the same.  I know the difference between the two and they aren't the same.  She also says something else is the same when I know it is different.  I just forget what that was.  I can't trust her - she's obviously nuts.  Help me, Please call the authorities.
