why am i in this biz?

One parent knowingly brought her child sick. I should have followed my policy and sent her home till he was better. My daughter kisses this sick child (infant really), gets sick. Kisses me and her brother, I am now getting quite sick despite lots of Airborne, zinc, Hall's, and anything else I can think of. With all the sneezing, I thought maybe it might be allergies, but now my throat is hurting, my head is stuffy, and I'm getting quite cranky. I HATE HATE HATE being sick!!!!!!!!!!!!!!!!!!!!!!
