Serenaitis is going around already
Chances are you have contracted Serenaitis if
...Upon viewing scheduled draw and after seeing Serena Williams
name in your 'opponent' column,
you experience the following symptoms:
Cold sweats before the beginning of the match (even in freezing temperatures)
Acute anxiety, followed by fear, worry, uneasiness, and dread,
Sudden Onslaught of Schizophrenia,
Deciding on a walk-over even after defeating your previous opponent by a comfortable margin (i.e: 6-1, 6-0),
Delusions of 'hope'
that you will defeat a far superior player,
Sudden loss of motor control after coin toss,
An abrupt and unrelenting desire to take a piss, even after running dry; or incontinence
during change-overs after being broken for the 3rd time in the first set alone.
If you have experienced one or more of the following, you should quit your profession and have a baby, or blame loses on bad fitting shoes or a shoulder injury.
