ALL traditions started at one point, just like everything else.
Although Englidh is not my mother tongue, I believe I have a better understanding of this situation than you, noob...
Oh yes, all traditions start at some point, but let's not get ahead of ourselves, shall we? For that matter, English isn't my mother tongue either, but a tradition isn't a spur-of-the-moment thing, you can't suddenly decide something is a tradition because it's been done like, twice.
So, let's recap. You've had a professional chair umpire telling you that no such tradition ever existed in tennis. Then, several of us gave examples of this "tradition" not being upheld in places like Wimbledon (where I understand they're pretty big at tradition). You and your pals countered that with a desperate "Oh, but it's a WTF tradition."
We then showed you that Ferrer was sitting on the left in the 2007 WTF final. So now it's "Oh, but it's a WTF tradition that originated after 2007."
Sure.
Let's keep having fun, then. Check the Federer-Nadal final of 2010. Nadal was #1 at the time, and guess where Federer is sitting? You've got it, on the left.
So that WTF-specific tradition didn't exist in 2010 either. Guess it must be a pretty big thing, then. (I didn't check matches from 2011 except the final, sorry--and you'll be happy to learn that, in this case, Federer sat on the left, as "tradition" warrants, yadda, yadda.)
So, either this is a total BS article (like some of us have been saying from the start, with tons of examples disproving it), or we're looking at a great, hallowed tradition that nobody except the infamous guy who wrote the article ever heard about, a tradition which is so cool and so far-reaching that it is apparently reserved for the WTF only, and which originated sometime between 2011 and 2012.
Do I need to tell you which of these two options gets my vote?
