Sometimes I leave mine open. I never even think about it.
I am too lazy to change something unless it is bothering me. So, usually the blinds are closed unless I need a lot of light for something, then they stay open until I am doing something that demands privacy and I close them. Could be days later. Then, they stay closed till I need light again.
I don't care if someone wants to watch me watch TV. If it is that exciting for them, let them look. What do I care. And if it bothers them to see that, then DON'T look in my windows.
