How do I factor in when a statement can be taken different ways based on inflection, volume and attitude?

I am struggling with how a sentence can mean something different based on how someone says it. It is the same sentence but with a loud and angry voice it feels different. Example….. ‘ I don’t care”…… can be taken different ways based on the way it’s said . It can be sarcastic or maybe they don’t have a strong opinion and don’t care . I feel like how something is said determines what the meaning is. If someone screams at you it changes how you feel. The factual sentence can be the same but it doesn’t feel neutral. I’m not sure how this part works.
I felt frustrated at my apartment complex after my apartment was broken into. I asked that residents be informed so they can be aware and keep look out for anything that seems “off”. They did not do that. I called corporate (twice ) and they did not call me back. I went into the office and voiced my opinion about being told they would put out a note informing of the break-in and the fact that I did not get a call back ( twice) from corporate.
after that they put a notice out and the notice on the door said…..make sure to lock your doors and don’t leave valuables in clear view in your car.
Safety is everyone’s responsibility .
No mention of the break in. I felt that the inference was that my break in was partially my fault. I had locked my windows and doors.
I am trying to figure out how to factor in tone . If I put my apt. put out a notice that said “safety is everyone’s responsibility ” …. that is factual in my C line- it doesn’t feel neutral.
So my question is how do you factor in the way something is said based on the tone vs. the factual words?
