Some people just love dogs so much they don't notice them barking. Many people are rude about dogs who bark and people with dogs who bark can become anxious that people grumble and complain she might have wanted to put you at ease by showing you she loves your dogs. Some people having a dog is all about meeting other dogs and meeting other dog owners. !
Or she might not like your dogs at all! She might have wanted to humiliate you and show you what a good dog behaves like! People do that if your dog barks and theirs is quiet they will sit by you so people will see they have a 'good ' dog and you have a 'bad' dog. They just have this weird competition thing going on in their heads.
It sounds though that she loved your dogs and didn't see their behaviour as problematic. She sounds more like the "Eh?..what commotion?" type.

We dog owners are a funny mix! It's lways good to be able to rant a little!
