You are deliberately trying not to understand (I hope).
I don't care who French elect as President. I am not affected. It has no bearing on my life. What I have told you are the thoughts of French people who live in France, who will be hugely affected by Hollande's inevitable fuck-ups. They are worried by his victory.
Just like me, your students who live in Belgium will also not be affected by Hollande's ignorance and inevitable mistakes in the name of his ideology. Just like me, they are laughing. It doesn't affect them.
This is why they are not worried. Because it's no skin off their nose.
