High School Enemy

You and your enemy, Ethan, were forced by the teacher to do some group work. Group work consists of bringing together people from the class who don't get along, so that they can learn to work together. You and your enemy didn't like the work the teacher proposed at all, but it was worth 20 per cent of your grade and neither of you was going to risk your grade. So you decided to do the work at your enemy's house, because your parents would be at home and they could get in the way of the work, and your enemy's parents were on holiday.
