go away bug

why is it, that on one of the busiest work weeks of the year, which happens to also be the week of my son's birthday AND the week before Thanksgiving, do I have to come down with a bug ......for the 2nd time in a month. Enough already.....I got things to do - not the least of which is knitting a buttload of Jayne hats and planning a party for 100. Calagon take me away.
