I don't have any children of my own, but my mother frequently blathers on about 'funny' things my brother and I have said/done. Personally, I think they're quite logical.
Aged approximately 3 years:
At a Church nursery group, discussing Noah's Ark.
Preist: And so God made a rainbow.
Me: No, he did not.
Preist:Yes, he did, how else would the rainbow have got there?
Me: When it rains the sun's rays hit the droplets and a "prison" is made, obviously.
Preist: Well, technically, you're right, but God still made the rainbow.
Me: Clearly, God did not make the rainbow.
Apparently, I become somewhat irrate over his misconception and ended up being removed from the church by my mother.
"Prison" = prism, btw.
And, last year, as a 14-year-old, when I really should have learnt to keep my mouth shut:
In a PSCHE class, where my teacher said that all opinions were valid and we were entitled to say them.
Teacher: What do you think about the earthquake in Haiti?
Me: The Haitian earthquake was a result of tectonic plate movement by convection currents, although it could be considered nature's way of reducing the quanity of excess living things.
Teacher: You cannot talk of culling humans like animals.
Me: As proven by my statement, I have the physical capability of doing so.
Teacher:Well, you shouldn't, humans are precious.
...
Teacher:Are you going to reply any time soon?
Me: Given the current exponential growth, humans are unlikely to become extinct in the near future.
Teacher:But, you can't go around talking about culling them like animals.
Me: I can, and demonstrated my ability to do so.
Teacher: But you shouldn't, it isn't right to talk about killing humans as if they were just animals.
Me: Humans are animals, and what makes humans more important that any other species?
(More inane waffling from my teacher. After which I decided to ignore her.)
So, I informed my mother, who then started to explain why certain thoughts should remain in one's head (a conversation I have somewhat frequently).
Me: If she had asked me my opinion on how I felt about the earthquake, I would have answered accordingly. (Admittedly, I don't see the point in aid, but I do have a rough idea of what I'm supposed to say in response.)
My mother then found it funny and uses it as an example of how literal I am to my teachers and her friends, and suggested that if my teachers didn't recieve the desired answer, they should rephrase the question.
