The worst thing about having a cold (and yes I have a cold, because yes I have a germ-encrusted toddler) is that by the time you are sneezing with a streaming nose and eyes, and you can plausibly take time off work, you've already been feeling crap for days.
I feel awful. That horrid post-nasal-drip sore throat, fever, exhaustion pre-cursor of a cold thing. I would love to leave work right now and just curl up in bed, but you can't see a sore throat, you can only vaguely hear it, and although I look a bit flushed and feverish it's just not convincing enough. I would definitely look like I was skiving off to go Christmas shopping.
God I feel awful.
