Dear Judy,
it (to be) long since I (to write) a letter to you. At last I (to be) in London. The weather (to be) nasty. It (to rain) all day today. I (to think) it always (to rain) on Sundays in London. Anyway, it (to rain) every weekend since I (to come) to Britain three months ago. I (to get) used to it, but I (to find) it rather dull. But I (to enjoy) my stay here as I (to make) a lot of friends here who (to come) from different countries. Some of them (to stay) here for a few years and (to speak) English quite well. I (to introduce) you to them when you (to come) here. All this time I (to try) hard to master my English and I (to think) I (to make) some progress. I (not to be able) to find the job I (to look for). I (to be) to quite a number of cities but so far I (not to find) anything suitable. My friend Peter who (to be) German and (to come) here a year ago (to find) at last a job at a German-British company. He (to promise) to help me because he (to know) that I (to learn) German for three years. I (to hope) to hear from you soon.
All my love,-
