You've just marked yourself as somebody who is very likely still in college and/or under the age of 25 and/or does not have spouse and kids and dog and cat, etc. :)
I submit that properly trained, "spouse and kids and dog and cat" aren't disruptive. I have all of those but a dog and work at home for hours at a time without interruption.
Now I remember I once discussed this with a friend of mine who is married and has a kid; he told that it's much easier to concentrate in the office.
So, yes, my bad, the first line should've been split in two.
