Another difference is the customs and traditions related to food. In Ukraine people try to eat fatty food, such as whole milk, sour cream, butter, etc. In the past people even went to villages to get whole milk because it was considered to be beneficial for children. The ironic thing is that in America we buy fat-free food because food that contains fewer calories is healthier. American food is different from Ukrainian.
Ukrainian people like to cook.
Americans are more used to the junk food. Also, there are differences in school rules. In Ukraine children study for only eleven years. They study with the same group of people starting from the 1st grade. Under these conditions it is really easy to make good friends and to keep those friendships even after graduation.
