Home sick

I don't think I've missed a day of work because of illness in 10 years. That's probably because until this year I didn't have a job that had any sick days available. Yesterday there were two guys who work in the same office as me who were out for the week with some kind of throat related illness. They worked in the office over the weekend. Sure enough, I started feeling something funny in my throat last night and it was worse this morning, so I stayed home and used my sick leave. I hope it doesn't get worse because even though I've got the sick days available, I don't like missing work.
