OMG! YES! Constant, constant, constant interruptions..and I only have a single family member in the house!
My husband is constantly calling me away from my writing to "come look at this article" (on the Yahoo news page,), or "How do you spell such-and-such a word?" (about every 2 to 5 mintues if he is writing comments), or, "Come look at this cat!" (we have 6 of the darlings, and one of them is always either into something, or striking a funny pose), in which case I'm also asked to "bring the camera!"
As soon as I get back to the office, plant myself in my chair, and begin typing, about 3 words later, I can just about count on another interruption.
He uses his computer in the living room, at the other end of the house, so he can use the big TV as his monitor...and his space at the opposite end of the office, in the same room with me, sits empty. It is, indeed, soooooooo very frustrating!
