Do you think people should stay in touch with family and friends when travelling?
When travelling, I prefer to be isolated from family and friends because its distracting. If I have to keep texting and calling people while on my trip, I won’t be able to fully engage. It might be difficult to immerse myself in the people and the culture, while constantly talking or texting on the phone.
Not to mention, its incredibly inconvenient and expensive to make international calls, and even with the internet, some communication apps like face book or twitter don’t wok in every country and finding the right app might be too much work. So, I’d prefer to enjoy my trip and then tell the猜词互动（人们） at home about it when I get back.
