We are not going through it, but I'll never forget the time my sister (with five boys) had them each break out ONE at a time with the chicken pox. She ended up quitting her job because she was out twelve weeks until they were all done with the ordeal!
That actually DID happen to me and my sisters when I was kindergarten. I have a younger sis so she wasn't in school yet. My older sister was a couple of grades ahead of me and we all got it one at a time...but pretty much in order so that we were all

at the same time eventually. We got better in order too. I remember how awful it was and still have a few chicken pox scars to remember it all by.
