Well I do miss my students (not all of them) after they graduate or if they move away ( I spend anywhere between 4 to 6 years with them and am very involved). But it never occurred to me that I would miss them if they stay home sick for a day. I also don't miss them when I stay home sick myself. It would be a bit much. I really don't see why my t would miss me if I miss an appointment. Seems strange to me. Maybe if I was their only client or they had no life outside of work. Don't know.
