What Did I do to Make Her Angry or Sad?

Question

I went to Korea for vacations and I contacted a friend.
She was nice at the time I contacted her and everything was just great.
When suddenly...
She didn't answer my calls and neither my text messages.
I sent her an email
And her response was
"I'm sorry to ask you this, but could you stop contacting me"
What was my error? My mistake that made her angry?
The only thing that makes me wonder is ciggs.
Though I never intented to smoke infront of her or even met her at the large crowded streets of Seoul, I did smoke and she doesn't like smokers. That's all. How could she even find me on the streets; my cellphone back there did not have GPS system on it.
Like WTF??
I did not even meet her this trip and all of a sudden I'm the bastard.
What was my mistake?

I don't date her or anything; we're just friends. Were, I mean.
I don't even know her parents either.

Answer 1

maybe it had nothing to do with you but her parents found out about you and told her to end the relationship. just some food for thought...
