A thermostat in a house will have a setting.

Similarly, if it is in your nature (your setting) to be pleasant even when feeling slight emotional strain, you will try to be pleasant. If it is in your nature to let it all hang out, you will let it all hang out.

I'm not necessarily supporting the idea that "there is no free will", but pointing out that it might be a nervous poodle's setting to bite me when I visit my friend. And it might be in my nature to throw it out the window without thinking when bit.

You see this in discussions where people talk about being to choose tea (which they don't prefer) over coffee (which they do prefer) in order to demonstrate their free will. Well, yeah - I guess. But if you're the kind of person who is designed to think it important to demonstrate your free will at the coffee shop, it's in your nature to take your disfavored beverage just to prove your point. Because that's how you are wired.
