Some movies and tv series would have you believe that it's totally normal for Americans to just switch jobs and move from, I don't know, Boston to Seattle and change their lives just like that every couple years or so. And maybe leave their parents behind thousands of miles away and only see them for Christmas if even.
Is that a thing?

有些电影和美剧会让你相信:“美国人每隔两年就会非常爽快地换工作然后从比如说波士顿搬到西雅图乃至改变他们的生活”是完全正常的。也许还会把他们的父母留在几千英里外,只会为了过圣诞节才回来看他们。
这是否是常见情况?
