Dear Topsy and Hetty!
I'm glad to hear that you are going to school.
But I want to tell you some rules you should keep in mind. If you are late or want to come in you should say :"May I come in?"
If you want to answer a question you should raise your hand, you shouldn't cry at all.
If you want to ask a question you should be polite and say : "Excuse me, may I ask you a question? "
If you want to close the window you should say :"Can I shut the window, please? "My advice is to be polite in everything. Use these words as often as you can : excuse me, thanks, thank you, May I . . . Can you. ...? and so on.
