Reality tv is not real. It is all scripted. And even if some participants are real people (not actors), the script will be forced upon them. If a person in a reality show would start to act real, it will be a scene soon to be deleted. The other actors will explain (tell lies) to turn the storyline back to the script. They are all fake people.
Please people, stop watching tv. Do not think of celebrities as real people. There is no reason to show interest in the lives on tv (e.g. celebrities and/or reality tv shows).
