And you're working away until late at night, and you're very, very careful, and you're drinking coffee and you're paying attention, but, occasionally, when you're copying this by hand, you're going to make a little typo, a spelling mistake -- substitute an I for an E, or a C for a T.
И работите до късно през ноща, и сте много, много внимателни, пиете кафе, и обръщате внимание, но само от време на време, когато я копирате ръчно, ще направите малка грешка -- правописна грешка. Ще замените И с Е, или Ц с Т.
