I found my first roomate's GF in the kitchen trying to boil a kettle of water. The kettle was plugged into a power bar but the power bar was not itself plugged in.
I politely (or so I thought) pointed out that the power bar was not plugged in thinking she'd realize her error and we'd chuckle.
Nope. She snarked back at me "SO?".
A little puzzled and bemused I said something like "Lemme help you with that" and reached to plug the power bar in.
"LEAVE IT ALONE!!" she barked.
Now realizing exactly HOW dumb (and nasty) this girl was I just shrugged my shoulders, said "ooohkay" and meandered on... but not too far because I wanted to see what would happen when the kettle didn't boil.
IIRC the following 15-20 minutes went like this (with me sitting in the living room within earshot of the kitchen).
@5-10mins: Some quizzical, frustrated grumbling and shuffling of whatnots.
@5-15mins: Increasingly frustrated grumblings with whispered phrases such as "[REDACTED] smartass such and whose and the like" (phrase paraphrased).
@15-20mins Girl calmly walks into living room, sits down with her cup of hot tea and casually takes a sip. I asked her in a Leslie Nielson-esque deapan "so... how is it?". Equally deadpanned she replies... "It's just fine thank you"... but oh the daggers in her stupid little eyes.
