What is the most profound thing a stranger ever told you about you?

I was out drinking way too much recently. I found myself sitting with a woman in the corner of a bar. She said she wanted me to know she had a boyfriend, and she just wanted to talk. I looked at her for a moment and asked “Do I come off the bad boy type?”. She said “You look like you used to be, and grew out of it.”

I am curious to hear if anyone else has been given insight into themselves from strangers, and to hear their stories.
