Why we don't smile

Heya all, i'm from Ukraine, i always communicate with russian guys, because we are a friends >^_^<
Many people from other countries can not understand why people from Russia and Ukraine don't smile? Answer so simply.
Do you know how much time slavic people work? 8 hours it minimum :)
Peak hour when we late, not all people good. And yes, almost always we have conflict situations in the bus. Many people are trying to spoil the day, and... they do it!
Our people are never satisfied with their salary, because this money they can spend just on payment of utility bills and some food.
We are dislike dissemble happiness like other, we are natural.
We don't smile because we bored, we don't have many time to rest.
And if you still thinking "They don't smile because they evil" go to a psychiatrist.
