Ahahahah...
When my oldest was 3 i did the same thing explaining her color changing night light...
I talked for a good 10 minutes about different wavelengths of light, and how we see them as different colors, and how the light bounces off of things and into our eyes...
The next few weeks, every night was "tell me about the colors"
My sis did that with a book about the Navy my dad had bought me. Being as stubborn as she was, we ended up reading/listening to that exact same book every day for 2 years. She tried to do it in a flat and bored voice, very quietly, very fast... But to no avail.
To this day, I still don't know jack shit about the Navy because I never cared, I just wanted to fuck with her as much as she was fucking with me.
