Sara is annoyed by her roommate bringing guests over and amount of noise they make. Her roommate has a job waiting tables and gets home around midnight on Thursday nights. They often bring a couple friends from work home with them. They watch television, listen to music, or play video games and talk and laugh. Sara has an 8 a.m. class on Friday mornings and are usually asleep when they return. Last Friday, Sara talked to her roommate and asked them to keep it down in the future. Tonight, their noise has woken her up and she can`t get back to sleep.
