Human beings come to instincts at averse situations to avoid the worst risk. You would run away with no hesitation when a tiger staying in a zoo cage jump towards you. Knowing the tiger is blocked by the cage would not help you because such instinct has been built in generations.
I wouldn't bother to analyse why most of us have the same instinct when we see another is at intimacy to our privacy. There is a recent example too. When Ravi turned on the video camera at Clementi, the instinct of some, if not most, opened up a Hate Crime. I am not arguing that it was not a possibility. It is a possibility with the lowest probability. Most probably, it would be curiosity. It was unfortunate that it is the curiosity that also has killed a cat.
I suggest you run away from your this instinct before it kills the family. In this case, that your mom is a family member of you is the cage. But this didn't help you coming to a harmful instinct. If you keep this instinct, it sure will ruin the cage--the family relation. By then, your instinct would become a reality.
