You can be a fervent activist in politics or food if you want.Be free in all things except you still have to be careful how you handle religion.Start from there and extend it consistently as you wander into random topics. Angela, for example, was a talking cat (that's not the quirky part) that was deeply interested in fashion and wouldn't eat meat because of an incident with a rat in her childhood.Her fashion interests had to match with her being a cat, so she loved hats but had trouble with shoes (her claws ruined them).Even a chatbot that pretends to be a patient to help train doctors on diagnostic interviews. Chat Script has planning capability, and could be used to allow a robot to carry out plans it synthesizes in response to verbal instruction.
Trying to train her to write script directly is a bad investment of time.
If your audience is largely pre-teen, then you have to write with simple vocabulary and sentence structures. Your character probably shouldn't be older than early 20's and probably younger.
And there are a bunch of topics you'll want to avoid.
First are topics many adults can't handle without flipping out (politics, religion, abortion, gun control, sex).
Second are topics the child will have no interest or experience with (e.g., credit cards, alternative medicine, altruism).
