We hired a BY teenager to babysit one evening. She asked me if she could use the computer to type some schoolwork. Since we don’t have internet (I’m on YeshivaNet), I agreed.
Next morning, my oldest daughter told me that Sitter had been watching a dvd that she had borrowed from local BPL, and described the parts she had seen until Sitter had noticed her presence and prudently closed the screen.
It was a dvd not certifiable as kosher by lenient standards.
