Dear {Name},
I'm truly sorry that I offended you the other day with my {joke/comment/action}. It was not my intention to upset you and I feel terrible that I may have hurt your feelings.
I see now how insensitive my behavior was. I didn't consider how you might take my {words/meaning}, and though I can assure you that I meant no harm, that doesn't change the fact that I really bothered you.
I will work hard to make sure that I am more considerate in the future, and I hope that you can forgive me.
Sincerely,
{Sender}
