Barbra: Hello, Mr. Patterson.
Patterson: Hello, Barbra. What's up?
Barbra: I can't come to work tomorrow?
Patterson: What's the reason?
Barbra: It's rather personal.
Patterson: Fine Barbra.
Patterson: I am counting though. It's your third personal day off this month.
Barbra: Appologies Mr Patterson. Will not happen again.
Patterson: I know. The month ends tomorrow.
Barbra took a day off on demand because of personal reason. It is third time this month that happened.
