Email says: 8am to 2pm
I get there at 7:30 so I have time to chit chat with new people and get a good seat. Mother fucking thing doesn't start until 8:30. The director said she wanted to be sure that we would all be on time.
This is a mother fucking grad school program. I would hope that you trust your students to either be on time or have a really good reason why they aren't.
