Woodlandmama's Bug That Wasn't

So apparently we don't have a strange bug that bites you while you sleep. Well, maybe Mr. Hobbitfeet and the kids do, but I just have Shingles, which is caused by the Chicken Pox.
The kids don't have chicken pox though according to their doctor (after she made me yank Boy out of school and rush him to her office). She confirmed he only had bug bites.
It's hard to imagine though since I only hang out with my husband and kids, how did I get exposed to chicken pox without them being exposed?
So I am in bed achy and bored. Who wants to play with a poxy mommy. Not my kids that's for sure!
