駄目

某オープンスタジオの昼クラスに出てみたが、駄目だな。名前を覚えている人にしか注意しない。先生が生徒に妙にイラついたような態度を取る。シューズをサンダルばきのままで教えているのも気になる。
I attended the studio lesson. But the lesson was not good. The teacher gave her advice only to the paticular people. I was completely ignored. And she seems to be irritating about someting. And she teaches with her heel side of the shoes stamped.
