Why do they need to over exaggerate any possible thing in life?

When it comes to the way you spoke to them, because of something they did that triggered you, they make out as if whatever you said is wishing death upon them, when in reality, you snapped at them and told them to stop. They have to over exaggerate that.

When it also comes to anything in everyday life, how much something costs to purchase or operate, how hot the temperature is, how much electricity or water you use up. Literally any possible thing in life needs to be over exaggerated by them. Why do they do this??
