Why Russians are always the bad guys for you?
A lot of it goes back to the Cold War and the events surrounding it (Space Race, Miracle on Ice, etc) - many people who were alive then are still wary of Russia (and I'm sure the reverse is true). The fact that both are world powers with often contrasting world views and strong and/or argumentative leaders feeds into this, especially for adults who put emphasis on politics.
Most educated teenagers and young adults have no negative opinions about Russia.
Putting personal bias aside (which is probably difficult due to having used it your entire lives), but do you think that Imperial is truly better than Metric? Also same question to MM/DD/YY vs DD/MM/YY
Metric: The metric system is indisputably better in most cases. Despite common belief, Americans are taught the metric system from a young age, tend to use it even more as they progress through schooling and careers, and as a result, most young adults actually know the metric system better.
Dates: As far as I'm concerned, both of those systems are awful. The best way is using an abbreviation for the month to remove ambiguity - 24 Jan 2019, Jan 24 2019, 2019 Jan 24, whatever. But if only numbers are being used, then it really doesn't matter as long as it's clearly stated what format is being used in an obvious place.
- What do you do in your free time if you cannot stay at home? Especially in city areas.
- I heard that everyone has a gun in the US. How true is that? How easy is it to get a gun? Is there an age under which guns cannot be gotten?
Free time: Most American cities have vibrant nightlife, generally things like nightclubs, downtown districts, outdoor malls, even bowling alleys. If nothing else, there's generally a variety of bars available in most places.
Guns: Many people own guns, more so in rural areas, but not all. You can buy them at specialized sporting goods stores, and in some areas you may be able to purchase some guns at a local supermarket (but still from a licensed dealer). They aren't particularly cheap, and you'll generally need an ID confirming your identity and that you meet the age requirements for the type of gun in question, and a clean record of both criminal history and mental health. Rural areas or areas where hunting is prominent often relax some restrictions. In some areas, obtaining guns illegally is not difficult.
