Cover art for You Were Right About Everything lyrics by Erin McKeown

At a show in Portland a couple of years ago, Erin said that the person she wrote this about thought she was being sarcastic. She says no, this is really quite sincere.

I wonder about the lines "there were times your age began to show / you were never more dangerous to know". They're open to interpretation and not further explained in verse afaict.
