sleep issues with an old man in the house

MonsterMustDie woke up at 4:00AM today. Then he made coffee and crept around the house before settling in front of his computer. Inevitably, despite his attempts to be quiet, the sounds in the house and the smell of fresh coffee woke me up. I checked on him and went back to bed, pulling the sheet over my head and I refused to get up until the alarm went on at 7:00AM. Three hours sleep robbed from me and, although I know it's nothing he can control about himself, I reserve the right to be disgruntled.
