Hi. I just wanted to tell you that your upstairs neighbor was very, very upset about hearing she disturbed you.

You mean she was very, very upset that I complained to you about it.

No, she was mortified to discover that she was bothering you.

You mean being bothered by constant stomping by her and her friends day and night is something she would be surprised by.

The point is, she is sorry

You mean sorry she got caught.
