Stuck on a desert island?
Started on 23^rd April by Steve Posts 1 – 7 of 42
Post 1 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 wouldn’t miss getting up at six every day to go to work, though! What about you?
Post 2 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
Post 3 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 wouldn’t miss junk mail(垃圾邮件) --- I hate coming home every evening and a pile of junk mail in my post box.
Post 4 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.
Post 5 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.
Post 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!
Post 7 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!
