I know that it\'s quite a while since I last wrote to you but for the past few weeks I have done so many things at the same time that I hardly had time for anything.

 Я знаю, что с тех пор, как я в последний раз писал вам, прошло немало времени, но за последние несколько недель я сделал одновременно так много вещей, что у меня практически не было времени ни на что.
