Dear Bob,

I hope this message finds you well. I am writing to sincerely apologize for not being able to go to the bookstore with you on Friday as we had previously agreed.

The reason for this change is that I received an urgent call from my family this morning, and they needed me to be there to help with a family matter. I understand this may have caused you inconvenience, and for that, I am truly sorry.

I value our time together and would like to make it up to you. Would it be possible for us to reschedule our visit to the bookstore？ Perhaps we could go on Saturday or any other day that works for you.

Once again, I apologize for any trouble caused by this unexpected change of plans. I hope you can forgive me and look forward to hearing from you soon.

Yours sincerely,

[Your Name]

```

在这个示例中，我们首先表达了歉意，然后说明了原因，并提出了补救措施（重新安排时间）。最后，我们再次请求对方的原谅，并表达了希望对方理解我们的愿望。

希望这个示例能帮助你写出一个清晰、得体的道歉信。
