Me being a Blaze the Cat fictive is funny.
Canonically she's so stoic. I don't have any canon memories with which to judge on whether or not that is how I used to be myself. Maybe.
I can put up a theory that I used to be like that too, because of feeling the weight of being a princess and the Sol emerald guardian, and it having been taught to me that my outward demeanor was expected of me. It sounds right. But, also I don't relate to the idea of having been how I am now behind that facade. I slightly feel like it makes sense that I would ease up and change once those duties were lifted from me. But, that also feels a bit silly. I'm trying to come up with a coherent story here when I neither need nor want one. Call it a thought exercise - it's nothing more.
It's just funny to me that I'm someone lighthearted and even giddy most the time, when the source of myself is someone who is so "not that". I can be calm and collected, serious, myself, yes. I've spent long periods of time like that while in our system too. But, that has almost always been when I was away from front and not interacting much with anyone (in and out of system). Or when something put me very much on guard. My preferred mode of interacting with the world is not very Blaze-the-Cat-like. I'm more excitable and vulnerable than that.
