My biggest challenge is learning how to behave at the dinner table.As you can imagine，things are different from the way they are at home.（3）.You're supposed to put it on the table!I thought that was pretty strange at first，but not I'm used to it.You shouldn't eat anything with your hands except bread，not even fruit.You have to cut it up and eat it with a fork.（4）.If you don't want any more food，you should just say，"That was delicious." Also you're not supposed to put your elbows on the table.I have to say that I find it difficult to remember everything，but I'm gradually getting used to it.（5）.
Dear Laura，I'll write again soon and tell you more about my life in France Hope you're having a good school year.
Yours，
