person A: I was in a back room in our house and everyone else was asleep. I heard a weird crinkling noise and was worried that someone had come in the house. 
person B: Oh my goodness_comma_ did you go to check what the noise was?
person A: I did_comma_ it turned out to be my cat playing with a play mat the kids left out. 
person B: I'm glad it wasn't anything serious! It's scary how quick our mind goes to the worst possible scenarios.
