So what defines a short term student and a long term student? Mary defined a short term student as being anywhere less than 6 months, but after she said that (and even after we finished recording this episode), we were still debating what differentiated a long term student from a short term student. Any way you look at it, hosting short term students and long term students can be very different experiences. In this episode, Mary and Erin go toe to toe on the pros and cons of hosting long term students versus short term students.
