High School free period

High school free period
The high schooler we have free period every week, which is day 1, day 4 and day 5. Day 1 and day 4 the free period is around 1 hours however Day 5 is only 20 minutes. Day 5 the free period is shorter than day 1 and day 4 because Mr. Travis have class with the middle school students. During my free period, I will listen to my music, chit chat with my classmate, doing work, read books, take a naps and playing with my phone.
