Sometimes people want to read someone’s text messages, messages that were not sent to them. A wife may want to spy on her husband to see if he is having an affair and is messaging with the other women. Also parents may want to see what their children and their friends are talking about. But even though it’s possible to read other peoples messages, is it ethical? Some say it’s necessary, but others think it’s illegal and unethical. I guess it depends on the situation, you should have some control over what your family is doing, especially if it can put them in danger.
