Who knows how many got the winter virus. This year it was quite fierce. Of course, don't complain. There is always someone who has it worse. If you drop a brick on your toe, you might yell ouch, even though someone might at the same moment somewhere be experiencing the pain of being run over by a delivery van, or having their limbs hacked off on the battle field. There's always worse pain and discomfort. Nobody is complaining. But it still hurts when you drop a brick on your toe and the winter virus was quite fierce.
Eventually it passes. The body emerges, weak, tired. Slowly get back on track.
