Aww....sorry to hear that maybe you will see her again. And maybe next time you'll get her number

About the phone thing, I think it's weird that people sit in public and talk out loud about personal issues and expect people to pretend they don't hear it. If someone is being particularly obnoxious .... I join in the conversation. They give an odd look and move away. Or on one occasion a lady actually turned to me and said "you're being rude." I replied "I'm being rude??....I'm not the one who's sitting in public talking loudly about the adventures of my va-jay-jay."

Anyway....I don't think you were being creepy to talk to her after what you heard.
