First of all, I have to say that I live in a town where there is people who speaks english and french. Some only speaks one language. I speak both, but I am still learning english.
This happened weeks ago but I want to learn what to not do. I was in a club with a friend and he was talking to a group of guy so I just started walking arround the club looking for some chicks. I was going to the balcony and I infront of me a girl was going to pass so I let her pass first. But in this club there is a window door you have to open before but she didn't see it so she walked directly into it.

It was so funny! She looked at me and I was still laughing. She smiled and came to me, put a hand on my shoulder and :
Her - (something in english)
Me - Sorry what? Do you speak french?
Her - Yes, a little bit (after this sentense we talked in french)
Me - Ok, next time, don't try to break the door, just push it.
Her - hahaha
Her - Do you understand when I speak french?
Me - Yes you speak well. Your accent is sexy (it really was).
Her - Walked away for a second...then came back and told me that she is ashamed about what just happened.
I didn't try to understand what she was talking about. I think she misunderstood what I said and maybe she thought I was talking about her. What I did wrong? It was too soon to tell her a compliment?
