Read quickly, the speaker sounds agreeable, even generous. They promise to say what people want to hear, to never let anyone down, to never be a burden. But look at what is actually being promised: the speaker will say only "the things people want to hear," not the things they mean. The title, "templated sentences," gives the game away. These lines read like phrases copied from a form, not words from a real person.
The short, flat sentences, each starting with "I'll" or "I won't," feel rehearsed, almost like a recital. The speaker seems tired and a little hollow. Judging by the language, the fear of being a burden or a disappointment has pushed them to hide themselves behind acceptable answers. The final line, about not straying from "society's templates," names the pressure directly. The mood is quiet, controlled and sad, with a hint of irony: the promise to behave is also a small confession of how much is being held back.
