Late Bus

I have gone to the public library after school and come back to find that I could take the late bus home.  I went to the library all the time to do homework and go to Anime Club.  Then I went home on the late bus.  But very recently they changed that rule and now nobody is allowed to take the late bus home, even if they were doing homework at the library.  That's not fair.  Who thinks that we should be able to take the late bus if we go to the library for school related work????
