Is the grass greener on the other side?

As a blog assignment, Professor McArdle told us to propose a contradicting argument to the one that we wrote about in our public writing pieces. Here is mine:

Getting rid of half days was the best thing this state has ever done. Children out and about on regular school hours causes much havoc to local businesses that do not normally deal with them during the day. During these half days, students are more liable to get into fights and make bad decisions, because they have so much extra time.
More importantly, students are now getting more classroom time. In many school districts, a half day would be seen as an "easy day" and students would not learn anything. Elementary students would just goof off while middle school and high schoolers would have shortened periods, which would barely give the teachers enough time to get started on a lesson before it was time to go to another class. Although teacher inservice is now virtually impossible, many teachers would complain about them anyway. They seem to find them boring and pointless. Getting rid of the half days now gives the teachers more time for instruction instead of wasting their time in a place they would rather not be.
