The morning classes at the high school went the same as always--the only true difference was that everyone was now sharing a body with at least one other person. Ty and his four body bros were still getting used to their new world order--or rather, town order since that was basically the full extent of the change. The teachers were able to teach more effectively, although the students were not exactly able to learn much better than they were able to in the original timeline. Ty wanted to be sure that history would not be changed too much, but that everyone in the town would simply believe they had all existed like this for their entire lives: wide bodies, at least two heads, etc.
At lunch, each body got one lunch for themselves--Ty had wished that each body had only one stomach. The heads of each body took turns eating at times, alternating between eating and talking with the others at their table. At least, this is what Ty and his body bros did at their table. They talked and ate with their own friends, who were also sharing bodies with body bros.
The afternoon classes were pretty much the same as the morning classes. Ty and his bros were able to wrap up a few papers during a spare period at the end of the day--another of Ty's wishes. They then used the time to talk about their new hometown...and possibly what else they could do.
Once the final bell rang, the countless shared bodies of students flooded out of the school. Ty and his bros went home to their shared house, awaiting the future that they could make.
