Car park reservation and ...?!?!

Peter told me that he'll have an appointment at 10 am on next Monday, and asked me to ask my parents at what time they'd visit him. At Peter'd reserve a car parking place for us previously, I told him 9:30 am as my Dad would just say hello to him and wouldn't stay too long. However, I heard something embarrasing from Dad on telephone at night - Uncle Yeh had asked some members in Tzuchi to get contact with Peter for Dad and, what's more, the appointment was said to be 10 am ...!? I'm not quite sure, but I have a feeling...could the appointment Peter will have at 10 am on Monday be ...???
