When you are not fluent in the language

,then you tend to create jokes out of yourself.

Example A:
I have friends (A & V) were getting married and A's family flew in from South America (She is South American). I saw her father once. On the day of the wedding, an old man accompanied her outside the Town Hall for the wedding registration. I approached him but was not sure whether he was A's father.
Me: Vous êtes le beau père de V? (Are you V's father in laws?)
Him: Oui. (Yes)
Since he admitted that he is V's father in laws, that means he is A's father, who was supposed to be a South American who doesn't speak French.
Me: Wow vous parlez bien français! (Wow you speak good French!)
Him: Bien sûr, je suis Français! (of course, I'm French!)
Then I heard hubby laughing heavily. It's just so stupid to compliment a French speaking good French. Apparently that guy is le beau père of V , but beau père has two meaning in French, it could be FIL or step father. So he is the step father of V, not FIL. How confusing!

Example 2:
During the class, I was chatting with my guys classmates.
Guy 1: How long had you married?
me: About a year ago we had our civil wedding, but just recently we had our church wedding.
Guy2: Do you have children?
me: Non, mais on est en train de faire. (no but we are making it)
Then I saw them all trying to hold their laugh, something must be wrong. I didn't dare to ask so wait until home I asked hubby.
Hubby: Of course they laugh lah, you were telling them you were in the process of fucking!
Gosh I swear this was not my intention, I wanted to say we are trying, not fucking.
