Exhibition class last friday

We had to discuss with each other what kind of exhibition we are going to make hipothetically, and It was interesting but I felt like we had too much time for it, as we discussed in like 5 minutes and in the rest 15-20 minutes we were just talking with each other. I know that the classes are actually too long, and already at least like an hour before the class finishes everybody is already deadly tired, and anyway it's friday, etc. It was really a bad idea to have classes on friday, as we can not pay attention because we are so tired.
Anway the exhibitions are going to be interesting, I think everyone had great ideas !It's a good lesson to do this hipothetically , because it won't matter that much from a real one. Of cours the problems which may arise in reality won't be there, but still I think it's a good excercise !
