One day, I was just minding my buisness, than all of a sudden, a strange thought came to my mind: What if I'm actually a year older than my parents claim I am? For a few minutes, I really thought that my parents made me believe that I was a year younger than I actually was. I have no idea how this happened. Maybe it's because of my good memory, and being able to remember when I was very young. For a few minutes, I really thought my parents were keeping my real age a secret for me, until I started thinking rationally about it. I couldn't come up with any possible motives or reasons for my parents to do such a thing, so my paranoia faded.
Has something like this ever happened to you?
