This will be the third xmas in a row that my dh and I have been ill. Magically dd has avoided most of our lurgi.
Last year it was my df who infected us, visiting on xmas eve in a right state saying he hadn't eaten and barely slept for three days, that the doc had been out to him, it was that bad.
We said "oh df, you should've stayed at home, we would have seen you when you're feeling better". To which he responded that he fancied getting out of the house.
Cue Christmas morning and both me and dh are soooooo poorly. I manage to make dinner but we hardly eat and then fall asleep while dd plays. We're ill for 4 days to the point where dd had to be looked after by relatives.
The year before it was my dsis bringing chicken pox into the house. I have no issue with chicken pox parties but maybe not at xmas and without prior warning. She just turned up and said, "guess what we've got the pox". DH gets shingles and dd got chicken pox for the second time.
This year dsis used my hairbrush on herself and her dc and then announced that she'd spotted a couple of headlice on them the day before! I have thick curly hair 
About 10 days before Christmas we had friends visit unexpectedly, which was lovely. Then I got ill, really ill, I had the worst diarrhoea I've ever experienced. I couldn't work and had to cancel parties and planned visits. When said friends heard they said "oh yeah we've had that it's nasty, still not shifted it and we've had it for two weeks"....meaning they were ill when they came to our house! (I did think we'd gone through alot of loo roll!)
The worst part is that they went hospital visiting that week too!
Now thanks to the 'compromises to my immune system' I've picked up a second, very nasty infection.
I won't be able to take part in NYE celebrations with my family and I still haven't been able to even see all of them because I don't want them catching this awful bug. I've lost so much weight and now my hair is starting to fall out. Again...said friend said this happened to them too.
I'm not saying that you should stay in bed with every sniffle and I'm all for soldiering on, but there's a difference between that and being thoughtless.
Are you poorly?
Is it really horrid?
Do you think it might be contagious?
Yes?
Well don't go and pass it to your nearest and dearest then! Do the right thing and stay away until you're better!!
Grrrr.
