Дорогой реймонд!   какой ты молодец, что написал мне, я тебе .  я хорошо себя чувствую и относительным бездельем. я стараюсь успеть и почитать и развлечься.  погода в санкт-петербурге последнее время постоянно меняется. по утрам тепло, светит солнце, но к полудню небо хмурится и обычно начинается дождь. иногда бывают грозы, но они быстро проходят.  в европе сейчас, должно быть, жарко, так что следи за своим здоровьем.  с наилучшими пожеланиями  твой друг  dear raymond,  it was good of you to think of writing to me, and i appreciate it very much.  i am indeed keeping well and am enjoying comparative leisure. i try to divide my time about equally between reading and recreation.  the weather here in st. petersburg has been rather changeable lately. in the morning the sun shines warmly, but by noon the sky clouds over and we usually have a shower. sometimes a storm blows up, but it never lasts very long.  it must be very hot now in europe, so take care of yourself.  best regards.  your friend
