Time travelers are watching you.
I have this idea that (of course) time travel will exist in the future, but it must occur in a way that will not disturb the "past" (our "present"). People can go to any location and look back on its past, and you will never see them watching you. So is it normal to be paranoid that people from the future are watching you at your most private moments? And I don't mean like taking a dump or having sex/masturbating since that's normal human stuff. Things much more disgusting that I don't want anyone (not even IIN) to know about. I guess a secondary question would be is it normal to have such dark/shameful secrets like this?
