УМОЛЯЮ СЕРЬЕЗНО ОЧЕНЬ НУЖНО И ВАЖНО УМОЛЯЮ

с чем я немного не понимаю здесь просто текст

Dear gloria, thank you for your letter. it was great to hear from you. sorry for not writing earlier, i was so busy. you write me that you are going to visit moscow. i'm so happy! i promise you will have a fantastic time! well, i plan to show you as many famous places as i can. for example, red square or tretiakov gallery. you know, every foreigner can't imagine moscow without these symbols. fortunately, the weather is quite hot here, that's why you don't need to bring warm clothes. but don't forget umbrella, because the weather might be changeable. to tell the truth, i'm a great fan of tv series "the bing bang theory", which is quite popular in usa. i'd really happy if you get me some stuff connected with this tv series. as for your visit, do you have any preferences in food? do you have any food allergies? are you a vegetarian? write me soon. best regards, vlad
