Dear (teacher's name), your absence from the class makes the class feel much less lively... we cannot wait for your return. We all hope you feel better! While you were gone the class did (you can fill this up with whatever your class has been up to). We hope you get better really soon and miss you very much!
I am deeply concerned about your absence. I am hoping that you have a quick recovery, i hope it is nothing to serious and you can come back to school as soon as possible. If you don’t mind me asking, why have you not been at school? Hope for the best !
Whitman had written a long poem and some of the readers might feel bored reading it, so he used this device to give some energy to it. Since anaphora is repetition, it keeps on getting in the mind of the readers thus giving emphasis to the ideas he expresses.
