A bug or an ill isn’t over and done with
when it starts to go away because
bugs/ills can have a life of their own and
always change their mind.
They could just as likely start to come back.
A bug or an ill is over and done with
when it  has finally gone away
with no chance of it ever raising
its ugly head  again.
But even if does try to show up
we will all be better able to deal with it,
to make it clear that ours is not
a very  welcome house
