Spring

Its (It's) impossible but I understood (understand) that the weather is really affect (can really affect/ really affects) on mood of people (people's moods/moods of people). You know the weather in Russia change (changes/can change) every day and the climate is harsh. People are kind but when you get up every morning and see dark (see darkness/ it is dark) and return home from job (work/your job) and again see dark its (it's) terrible. You begin to be surly with other people. But spring already has come!(has already come) Sun is shunning(shining)! May be (Maybe / perhaps) people from shunning (sunny) countries don't understand me but it's really cool! You go for a walk and smile, you drive the car and smile! Is seems that everybody smile for you(smiles at you) I like spring.

Good stuff. A few mistakes here and there but the meaning of the passage is clear. I like Spring too but Summer is obviously the best! :D
