Dear Laura,

Thanks for your message. Yes, I’m having  a great time on my exchange program in France. It’s even  better  than I thought it would be. I was a bit nervous before I   arrived  here, but there was no reason to be. My host family is really nice. They go out of their way to  make  me feel at home. And you  wouldn’t  believe how quickly my French has improved! I’m very comfortable  speaking  French now. Although I still make lots of mistakes, it doesn’t bother me like it used to. My  biggest  challenge is learning how to behave at the dinner table. As you can imagine, things are really different from the way they are at home.  For example, you’re not supposed to  put  your bread on your plate. You’re supposed to put it on the table! I thought that was pretty strange at first, but now I’m used to it. You’re not supposed to eat  anything  with your hands except bread, not even fruit! (You have to cut it up and eat it with a fork). Another thing is that it is very rude to  say  you’re full. If you don’t want any  more  food, you should just say, “It was delicious.” Also, it’s rude to put your hands  in  your lap. You should always keep your hands ,but not your elbows, on the table. I have to say, I find it difficult to  remember  everything, but I’m gradually  getting  used to things and don’t find them so strange any more. I’ll write soon and  tell you more about life in France. Hope you’re having a good school year.
