Well, the only reasons I can see that she is a "bad teacher" are that she is not talking, and that sometimes she pushes and sometimes she pulls her pen; I understand one has better control if one PULLS the pen! Am I right?
+Gamze Soydoğan - I like it better than "Bad Teacher"! Thank you for giving us your real name! Your video is very good and clear though! I like your music too!
