There are days I DREAM of closing for a sick day. Laying on the couch with nothing to do and pretty much guaranteeing that I don't get up. It has been a few years since I have been sick to that point.

I wouldn't close for a runny nose. You won't get rid of them until about July. The runny noses seem to go from one to another and then you get a week or two of dry noses and then someone starts again. No big deal.

personally I try to ensure that I get lots of Vit C and my own kids do and then we do lots of hand washing and nose wiping.

I hope it works for you though
