Дорогой Алан!
Мне представился случай осуществить свой первоначальный план и приехать в Англию в августе. Скорее всего это будет в середине отпускного сезона, и хотя перспектива увидеть тебя снова вдохновляет меня, тем не менее я бы очень не хотел, чтобы ты терпел из-за меня какие-то неудобства. Не мог бы ты написать мне и сообщить, каковы твои планы на лето? Я очень постараюсь приехать в такое время, когда это не нарушит никаких твоих планов.
Надеюсь на твой быстрый ответ.
Твой

Dear Alan,
There is a very good chance that I might be able to follow the original plan and come to England in August. Most probably it will be in the middle of the holiday season and though the possibility of seeing you again makes me look forward to my visit all the more, I should hate to put you to any inconvenience. Could you possibly write and tell me what your plans for this summer are ? I shall do my best to call on you at a time you could receive me without upsetting your own time-table.
I hope to hear from you soon.
Yours,
