What’sup my man! When to do nothing, then nothing happens. Or am I mistake? If you agree, that you have to sense me why I send you it is letter. Because I was tired of lonesomeness and I wish to have this little happiness when I will feel amour, support and understanding of the my dear person. And if I think you rightly, that you search the same. You accept with me? So there mayhap it is writing will the beginning for execution of your wish. I do not know how to start that you make out why I write you.......
