My headteacher is obviously becoming older , but she is still very enthusiastic and energetic in teaching .However ,students in my class do not normally give her some feedback,because we are all so exhausted. Our headteacher is very responsible towards doing things.Many of my friends all like her very much.Because together we can get along very well.She is very easygoing.I have learned one thing from her ,which is ,No matter how tired I am ,I will have my day enjoyed energetically and happily.
