Sorry for not writing for a very long time. I got a cold. Actually I still have some health problem - my voice isn’t quite alright. You know, it’s a really big problem for me. Firstly, because of my work. I am a teacher, so my voice must be clear and loud. Secondly, I have two little children and it’s difficult for me to speak with them. Thirdly, to be ill is so expensive in these days.
