Stuck on a desert island?

Steve

USA Hi, everyone. What would you miss most and least if you were stuck on a desert island? For me, it would be the changing seasons in New England. I guess this will sound stupid but I’d probably miss the rain, too. I would not miss getting up at six every day to go to work, though! What about you?

Tomas

Germany Good question. Steve, I think I’d miss different types of bread, and shopping at the supermarket. I’d miss the food most. What would I miss least? My mobile phone---I’d like to be completely quiet --- at least for a little while

Paola

Italy I would miss the company of people because I know I’d like to have someone to share experiences with. I’d go mad on my own. And I sure would not miss junk (垃圾)mail--- I hate coming home every evening and a pile of junk mail in my post box.

Miko

Japan Hi, I would miss Manga cartoon, the internet and Japanese food, like sushi. I’d also miss TV shows and shopping for clothes… In fact, I’d miss everything.

Roger

UK I would miss my daily newspaper and listening to the news on TV and radio. I’d feel very cut off if I didn't know what was happening in the world. What I’d miss least would be traffic jams in the city, particularly my journey to work.

Past 6

Jayne Why hasn't anyone mentioned their family? I’d be lost without my husband and two kids. They’re the most important for me. And I can’t get started in the morning without a cup of black coffee. I wouldn't miss doing the housework!

Jaime

Mexico It would have to be music. I couldn't live without my music. I wouldn't miss going to school at all or doing homework!
