Dave's Brain is Crushed with a Metaphorical Falling Goal

I endured seven hours of a soccer referee certification course today-- we viewed hundreds of slides, I took many pages of notes, we watched many videos of entertaining fouls, and now my head is swimming-- I am realizing it's really hard to make the correct call in real time (it's even fairly hard when you can replay a video several times) and one of the teachers -- a British fellow-- was a real stickler for using the proper terminology, which is tough because all kinds of Americanisms have crept into our parlance-- it's properly called the "penalty area" not the "penalty box" and it's a yellow card for "unsporting behavior" not "unsportsmanlike conduct"-- unsportsmanlike conduct is a fifteen year penalty in American football . . . and here's a situation the entire class got wrong:  if the goalie has possession of the ball and one of his own teammates punches him in the face, then because this is a striking foul during the course of play, the other team is awarded a Penalty Kick . . . so the moral here is don't punch your own goalie in the face when he has possession of the ball-- no matter what he said about your girlfriend (or whatever prompted this hypothetical insanity) and I also learned when to downgrade a DOGSO red card to a SPA yellow card (and a PK) and other such technical issues, such as the difference between SFP and VC . . . SFP is serious foul play and VC is Violent Conduct-- SFP occurs when there was some attempt to play the ball but the foul is excessive, VC occurs when there is no attempt to play the ball . . . both are red card/sending off fouls but VC is a worse suspension-- you also need to check the five S's-- shirt, shorts, shinguards, shoes and socks . . . and most importantly, make sure the goals are secured with sandbags or spikes, because occasionally players get crushed by falling goals . . . so that's priority number one-- and I'm sure this is a job like teaching, where you need a lot of experience and practice before you start to get things right-- I feel like I'm starting this path a bit late in life (there were lots of teenagers at the course!) but I think i'll get a better idea of what it takes tomorrow when I go to Newark for my field session.
