I called lightsabers "life savers" when I was young.
Same here. I remember having an epic argument with my mom when I was 4 or 5 ('81 or '82) over my belief that they were Star Wars "vases" and my mom trying to say "no they are bases. You put flowers in a vase." :lol
Up until 94, I probably hadn't seen any of the movies since 85 or 86. I always thought that in ROTJ the Death Star was still the original with damage from the ANH battle. I didn't catch the dialogue about it being under construction.
I don't think I ever thought Vader or the Stormtroopers were robots. I think I always thought they were people.
