LMFAO you have a good memory. I haven't lived with my sister for nearly 5 years now, so that was definitely a while ago.
I never said it happened all the time though. It only happened that one time. I remember posting about it too, lol. Shit was annoying. That's what bedrooms are for, don't hold the living room to ransom.
Although I'm fairly sure me and my wife did the same thing a few times, haha.
