Answer: I always go to school
Step-by-step explanation:
Since you are writing a letter to your class teacher, first, you must write your full address and name, then the address your teacher has and the date. After that, you can start writing the letter.
Dear teacher, I would like to ask you to help me with this situation. I need two days of casual leave because I would like to visit my sister in another town since she has her birthday and I would like to be next to her. I am appreciating everything that you have done for us ad that we can always ask you something like that. I decided to have these two casual days on the day of her birthday because I was going to school the entire semester without any missed class, I wasn't even sick the entire semester. Think about it and let me know.
Thank you!
