It's good to do favors for your roommates.
John sees that his roommate Bob is running out of time for a deadline, and stressed about taking time for housework.
John wants to respond to Bob's worry.
John gets up and does the dishes and vacuums the floor so Bob has less to do.
John tells Bob he should quiet down while cleaning, because John is trying to play video games.
Bob is relieved and saves time and thanks John for the help.
Bob feels even more stressed, and becomes resentful of John's attitude.
