It is really difficult for me to write to you, because I know how embarrassed you were this morning for my impulsive statement. I feel very guilty and I should have been more aware of and sensitive to your feelings. While your timely help rescue, but my wayward words made you feel difficult situation.
I hope that you never mind my bad behaviors. I'll be sure to note the occasion speech never again will I even think, much less make a remark like that.
I hope that you can forgive me from the bottom of your heart.
I have seen your mail. I believe you do not mean to say that. Even though I am a little bit embarrassed but I can understand and sympathize with you. Moreover, it has been past and has not much effect on me. So you do not have to self-blame. I hope such things never happen again in the future.
I am very happy that you can recognize your problem. I think I was really a little angry, but only for a while. Because I know you're a good child. You may still be very clear what you can speak in public places. We are close friends, but you must pay attention to your words later, which will help you develop your interpersonal relationships.
