Once Christina appeared in my life. Girl that lived in a house at the end of our street. It was quite ordinary. We went for a drive on swings, and then she looked in my side and asked what my name is. She is strange enough, and always carries one red thing though.

I want to describe my favorite teacher. Ste taught English as well. She just loved what she did. At first, I can't stand learning foreign language, but she generated interest in her students and in me too. She created lesson plans tailored to their students' levels of ability, she noticed that I prefer to associate words with their meanings. With her great support, I realized how is important to know English. She haven't got a good sense of humour at all, but she could capture students' attention and only school's bells could stop her. I can tell about my English teacher more,but all you need to know about her that she has boundless energy to teach students, she changed my life, because she had high expectations of their students.
