My mentor blabbed on about rules, books, behaviour etc. , and took up all of our morning. Then it was time to go to lunch, and again, I followed the main stream. I saw this girlwith whom i exchanged a few smiles with during class, and asked if I could sit with her. And BOOM, I had a few friends, because she already had one.
So don't be afraid to approach people! Everyone is probably just as stressed as you are. Like litteraly, my friends only met a few seconds before I introduced myself, because they were lonely as well!
Then we did a visit of the school, wich was HUGE, 1400 people go to my lycée! Like what even haha!
