Trying to be present in my class, Parsa's dad returns back home sooner than other days. He and his spouse have always helped me and their son to be more advantageous in the class and during weekdays they can solve most of the problems that Parsa would face at his practice time. I think they've got the point correctly and have found out that parents are the second teacher for their children whenever teacher himself is away. Parsa is doing very well. Not missing even a single day, his daily practice time often exceeds half an hour. Here I'd like to thank him for his impressive job.
