"Ugh. I literally cannot with this family."
Big Sis has been unimpressed since the day she was born. Family legend says she looked up at the doctor, sighed, and went back to sleep. She has worn headphones every day since she was nine, and nobody is sure whether there's actually any music playing.
She finds everything about this family embarrassing, especially the farts, and especially in public. When one goes off, she rolls her eyes, says "So embarrassing," and leaves the room immediately.
Detectives would like to point out that leaving the room immediately is also exactly what a guilty person would do.
