Do you love to use your computer? My daughter does. She's on it more often than I will admit out loud. And I let her. Willing. Why? Because she uses her power for good. Right now she's writing a novel. She's written 30, or something like that, typed pages! It's hard to take away something that 1. she enjoys, and 2. she's using for better-than educational purposes.
She does not, however, like me taking pictures of her, especially when she's trying to work. This is her, I'm-annoyed-get-that-camera-out-of-my-face, face. So of course I then take her picture. Every time. :-)
