Subject: I’m on holiday!
Hi Jim,
How are you? Sorry I haven’t been in touch. I’m in the south of France.
My family and I are on a cycling holiday. It’s excellent! My legs get tired sometimes, but Mum has chocolate to give us energy. That helps!
We cycle to different places every day. At night we sleep in tents. We have also been swimming, visited a museum and walked around a castle. We usually have meals in a restaurant. I really like the bread you can buy in the bakeries here. It’s delicious.
We have been here for a week, and I have made friends at the campsite . I miss you, though. Maybe you can come with us next year.
See you soon.
Karl
P.S. Here’s a picture of me that Mum took. This is really the best holiday ever!

A We have eaten fish, steak and lots of potatoes, but we haven’t tried snails or frogs’ legs!
B I like it because I look happy and I am having fun.
C The weather hasn’t been very nice, so we haven’t gone outside much.
D I have never done so much exercise, but I am really enjoying it.
E I have learned a new trick on my bike from them.
