My oldest daughter has had several absences from school lately due to illness. She is now having to petition the school to keep her credits and be able to graduate, and make up all the work she missed. I can't help but look at the different attitudes of the teachers, and their willingness, or not, to work with her in making up the work. Some have said that she was an "A" student before she left, and has been getting "A's" since her return, so no problem, but others don't even want to give her the school alotted time to make up the work she missed. All you can do is stand by, encourage her to keep going, and shake your head at some of the attitudes.
Hang in there. Stick
