Well it was a few months ago, so I dont remember, but since she sad it after I kept pointing out "when have you seen someone do that" is not a good reason not to do something a more efficient way, I probably just stared at her with the silent understanding that anything I say would be pointless. That or screamed something at her back and angrily went into my room (and then came back out few seconds after cause we had to finish doing it and I didn't want my internet cut).
