Marching Band!
Lot's of you don't know this about me but I'm in marching band (lead trumpet bitches), and it takes a LOT of my time. So much that I've calculated the hours and it is more required for me to have a full time job, not including school. Check this:
Weekday practice in the morning- 7:30-9:45
Thursday night practices- 6:30-9:00
Friday night rehearsal and game- 5:00-11:30, pushing midnight
Saturday competitions- 8:30AM-11:00PM. Although the times vary per competition.
That's 36 hours, and assuming 'full time' in America is 32-40 hours a week, I carry a labor intense full time job, and I don't get paid!
