Don't be afraid to make mistakes and speak French.
I was a volunteer at our county jail working with Hispanic prisoners. One Venezuelan woman had been in the U.S. for 7 years and didn’t speak a word of English. She said she was afraid people would laugh at her if she made mistakes so she would never practice. She was being abused by other prisoners and couldn’t ask the guard for help.
Make mistakes in practicing French. The more the better.
