And what about empathy for Sue, the LBS? If you know anything about Sue or her sitch, you'd realize the "Why the F are you still calling her" is not her usual approach. (And she admitted that after a night out, it was a mistake to bring up the phone call.)
The hurt, pain, and despair that a LBS goes through is horrendous. We GAL and act 'as if' but we're only human after all. So she lost her temper. After all she's been through with her H, I don't blame her. Sometimes it's simply a matter of how much crap you want to take.
They say compassion is a 2-way street, and I say empathy is as well.
