Yes, very much so. I am way more relaxed during the hours when there won't be knocks at the door, phone calls, emails etc. and it's always the best time for me to write prose or code.
Even if I'm out for a walk in the countryside, I get resentful if there are other people hanging around my favourite spots, spoiling the peace by being noisy, or even just saying "hello" as they walk past. I know this is very selfish of me, and they have as much right to enjoy these places as I do, but I can't help feeling it as a violation of "my" sanctuary.
