Angry might be overstating it, but... "A little. Yes. Or just didn't want me here. I'm not easy to live with." Screaming nightmares multiple times a week. The strictly regimented schedule and difficulty deviating from it except in cases of emergency. The time spent cleaning guns and sharpening knives, though at least now they can do that in their own room instead of the kitchen table. The fact that they're a large human-shaped thing taking up space in a not super big house.

There's good things, too, of course... but the Soldier is not really great at recognizing those as benefits to their housemates.
