Tired tonight

I am soooooo tired and I don't know why. Bleh. Boss is sick again and she texted us saying her husband came home with a 102 fever. Wonderful. I refuse to get sick again. This weather is not helping at all. Normal winter weather and then boom -- 40's and it's supposed to be in the 50s this weekend. NOT healthy at all. Oh well. Guess I'm going to go to bed early tonight. I can't stop yawning.
