My h came out with this kind of stuff to - I think it is becasue they don't really know what to do or say. I don't have a lot of suggestions but remember to do a 180. If it is annoying you try 'acting as if' you appreciate his concern or something.
Grrr... I agree with you though - very irritating. Don't you wanna just say 'hmmm, yeah everything is JUST dandy - what do you bloody think???!!!!'
