Quiet for writing...I don't need quiet.
In fact I prefer ordinary noise and actions happening around me. I write in the living room, with the dog and cats around. My husband is generally there too, reading or watching TV. My college daughters might breeze on by in or out the front door.
I have a small office area set up in my bedroom, but I am just not productive there.
Plus my dog Baxter comes and barks at me--he hates it when I am in the bedroom! He wants hubby and I to be in the same room.
