No doubt I shall have to see the old lady who is, so far, 27 mins late for her appointment.
On the other hand she might not show up at all (I hope not, because if she does and I refuse to see her because the next person is waiting, I will get scandalized and disgusted looks from the other patients in the waiting room; after all, she is very old.)
If 8.45 a.m is too early, (and I don't book the appointments) why don't they ring to rearrange? The snow is nearly all gone and she doesn't live far away.
