There was a long time I didn’t write to you, and now I have a little freetime. Winter is behind us and therefore I hope that you wouldn’t mind on such a long period between my last letter and this one. You know how it is.The sun is shining, trees become green and it’s difficult to stay closed among walls. Sometimes when the weather is sunny I go to walk through the park near my lodging and enjoy looking the children playing. You know, the day before yesterday while looking through my window I saw the wet street and people with umbrellas rushing for money and prestige. I suddenly remembered last summer that belonged to us. I suppose that you were not angry to me what happened. I think that it is not good to discuss about passed feelings.
