Never had them. I have had the cheap plastic miniblinds, hate those. I have 2 inch white wooden blinds now. They are easy to clean, let in light when open and close well at night to keep out the light in the morning. They also look nice open or closed. The dogs do not mess with them. There was a time when I did not have blinds at all. I liked the openess of the windows, enjoying nature coming into the house.
It took a lot of planning and saving to install them. I have about 18 windows. Now that I am older and living alone it makes me feel safer to be able to keep the blinds closed. I keep the ones at the front of the house closed and open the back ones for sunlight and view.
I always check across the street on my neighbor. She is a new widow of about 2 years. She is older, about 84, she always open her kitchen blinds that face me in the morning. The neighbors know that if they don't see or hear the dogs out there might be something wrong at my house.
There has been one time the neighbors called the police for a well check. Yes, I was sick but it was nice to know they knew something was wrong.
It was the same way when my mother lived on the next street over, if the blinds were open, she was good. Yes, I did a drive by every morning when I was working.
