The 5th season

So I am wondering why they never put the fifth season in the books?  You all know the one that I am talking about, it's the one that starts in late August when school starts and ends sometime around early to mid January.  It's the bug season, yes the bug season when every kid had a constant stream of green running from their noses and a cough that seems to sneak up on them so quickly that they never have time to cover it.  My youngest just started Kindergarten this year and already this bugs have hit.  Just this week, she missed the whole week of school with a fever and gallons of snot that just wouldn't go away.  We took her to the doctor and after a $60 visit the best they could tell us was, well is must be viral because nothing is testing positive.  Then we say, well what do we do then?  The doc says Motrin and Tylenol with rest should do it.  Well it's almost been and week and whatever this poor little girl got, she is still battling it.  This time of year stinks.  Hope everyone else has better luck with the bug season.
