Oh, it is sadly to hear that you are available till noon on Sept. 7th. Now I’m making adjustment of my schedule.
But I also have another appointment and it seems difficult to adjust it now...
In that case, is it really difficult to change our meeting date from Sept 7th to Sept 8 or 9th? Could you please double-check your schedule?
Sorry for inconvenience, but thank you for your kind attention in this matter.
