Oh yeah - my sister-in-law. She does my head in.
If she is going to even load the dishwasher, she announces it and heralds every minor detail whilst pulling on marigold gloves:
"Right... I'm just going to scrape off the remnants of the dinner from the plates into the kitchen bin, then I'm going to load the dishwasher and....."
It's the same with EVERYTHING she does.
My wife is nothing like her thank God, and just quietly gets on with things in half of the time.
