Everyone in this neighborhood leaves their windows open. Some don't even have curtains in their living room or dining rooms. The house we moved into didn't have anything on the dining room windows. You could see right into our dining room, living room and kitchen. I don't like the thought of people passing by (like the OP) looking at me eating so I close the curtains I put up a few months ago when I am fixing dinner and when we are eating. I leave them open the rest of the time. We live on a rather busy street. I'm not used to such a busy street, I haven't made up my mind if like it or not. I do enjoy all the people who walk by from sun up to sun down but the cars that drive by gets a little old.
