Dear Austin Parker,
We are extremely disappointed to cancel our dinner party, which was on December 2, considering our initial excitement at your acceptance of the invitation. We had to cancel the dinner as our son is getting engaged and the couple will be getting married this Monday.
We will host another dinner after the wedding. Till then, we are extremely sorry for the inconvenience.
Sincerely,
Iyan gale
