Dear Bob,
I’m sorry to tell you that I can’t go to the bookstore with you tomorrow. Something urgent came up and I have to deal with it.
I really wanted to go with you and see the new books. I know you are looking forward to it too. Please don’t be mad at me.
Can we reschedule our plan? How about next week? Please let me know if you are available.
I apologize for the inconvenience and hope you understand.
