In Maine, we consider Connecticut more part of New York than New England. And we consider it normal CT behavior to be sometimes crass and take opportunity too far. Obviously, we can not paint all CT residents with such a broad stroke, but it's exceedingly common, making it easy to self-justify (and I think self-justifying is often faulty). I too bet she forgot about it quickly.
I believe we should forgive ourselves (in the same manner and expediency we'd ideally desire forgiveness from others or offer forgiveness to others) but also recognize and learn from mistakes.
