I’m very sorry for not coming to dinner and making you wait for a long time. I forgot about our plans because I was busy with some work and lost track of time. I feel bad because I know you waited and I did not inform you.
I understand that it was rude to keep you waiting and I regret my mistake. To make it up to you, I would like to invite you to dinner again, and this time I will be sure to be on time.
Thank you for understanding. I hope we can meet soon.
