So I am in Mexico City. I learn Spanish. I work very hard.
Mexico City is much larger than Cleveland, and it's more interesting. I think it's the best city in the world. But there's too much traffic and smog, and there aren't enough restaurants with American food, but I like it. All of my teachers are very nice. Some of them are better than others. None of them speak English to us, so we all have to speak Spanish.
I'll write again soon.
All my love, Mary.

Tom, Thanks for offering to chair tomorrow’s meeting for me. Apart from Sally and Dave, the sales staff …needn't.. attend, but the Personnel people …mustn't.. miss it, as several matters concern them. You …needn't.. mention the new offices – we can deal with that later and you …needn't.. discuss the changes in the computer course timetables since they’re not urgent. Don’t forget that you …mustn't.. mention the visit by inspectors – we don’t want people panicking. You …mustn't.. forget to bring up the matter of the Smithson contract, and you also …mustn't.. leave out the new manager’s appointment. You …needn't.. go into details unless people have questions. But remember you …mustn't.. give anyone the idea that their job is at risk because of this. Make it clear that employess …needn't.. speak unless they want to. Last but not least, you …mustn't.. mention the staff-party Mr. Jones wants to announce that himself. By the way, you …needn't.. take notes, as my secretary will be there to do that. Thanks, Laura. 

Саманидское государство (перс. امارت سامانیان‎; Amārat-i Sāmāniyān) — государство, существовавшее в Средней Азии в 875—999 годах. Правящей династией были Саманиды. Столица государства — Бухара. Правление Саманидов ознаменовало новый период в истории «Иранского культурного континента», известный под названием «иранское интермеццо»[7], длившийся с IX по XI века и характерной особенностью которого было приход к власти, после 200 летнего арабского господства, коренных ираноязычных династий и возрождение персидского языка и культуры
