You are brilliant, I am not. I am sorry to have hurt you :(
You display abundance of patience & tolerate me, sorry, would take care next time.
I am sorry, my actions really hurt you. I am feeling sad about it. Won't repeat.
Your smile means a lot to me, sorry to rob you of that. Won't happen again.
I know, I shouldn't step on your toes. Still I do. I am feeling sad and I am sorry for the same. Love you!
