Dear HENNERY SMITH,
Let this letter serve as confirmation of my absence from work for the next three days. I spoke to Mrs. Williams and she advised me to email you. My mother has fallen very ill and I must travel to Dallas to be with her.
I spoke to Mrs. Williams today and she advised me to email you personally. I hope you will be able to find a replacement with such short notice.
I will stay in contact if anything changes but I do anticipate being home to teach next week.
