In many forums, I have seen people keep saying to avoid repetition of the same word in a paragraph. But in the sentence like below, how do you avoid the repetition?
Suddenly, the dog stands up and stares at something in the hallway. A shadow of something enters the living room from the hallway. The dog continues to stare towards the hallway.
I have to repeat the word hallway three times, and see no way to avoid it. Why and how should I avoid?
