You're worried about going outside in case you infect anyone else so your house is under quarantine, and you have a limited supply of paracetamol left. Everyone is still cranky and you're worried how much worse they'll be if they don't get their supply of painkillers. Children who have a fever and itchy skin aren't going to be angels, but neither will a grown man for that matter. Always make sure that you have a stock of pain killers for these kind of emergencies.
