How much does a person's eye color change as one grows up? Is it usual for someone's eyes to change from during adolescence randomly? I remember being told by friends during high school that my eyes were green and not believing them because my mother had said they were grey. Is it more likely that my eyes changed color but mom did not notice because after a while you stop paying attention to those details if you don't expect changes and my friends noticed because they were seeing me with a fresh point of view - or is it more likely that she was doing that thing were she expected me to be just like her and any evidence that I was something other than a clone was to be ignored? (Not exactly gas-lighting, but kind of similar in effect.)
