The sound of snoring. More specifically, the sound of snoring during the day.
Housemate snores. I can handle it overnight when she's in the next room. Once I'm asleep, I usually sleep like a log.
But she gets up early when her puppy needs to go out, and camps out on the lounge rather than going back to bed. She then lies there, eyes closed, snoring up a storm.
I have told her, many times, 'just go back to bed'. Oh no, she is awake, she knows she's snoring, but she is awake... Yeah.
On Sunday it was bad enough to rattle the windows. I was sitting in the lounge chair next to the lounge, having my morning coffee. It had been going on for nearly two hours at this stage. It was enough... I went out and took some frustration out on the garden - things needed pruning anyway. Still she insists she's awake. I told her if she's awake and breathing like that, she needs to see a doctor!
