Left (over there) is an alleged symbolic representation of disbelief.
Apparently, in my person opinion, but with out prejudice, and since I have fingers, um... the three hand movements represent a short cut to expressing three words that just about expresses pretty much anything really - WTF.
Using your hand means you can save having to use your mouth... not that I have anything against mouths, or hands for that matter, or other forms of communication like pens and keyboards, whiteboards and/or blackboards... (wipes beads of sweat from her brow)...
And cutting words up, not writing them out completely is great, economical in fact cause you drop vowels as opposed to buying vowels. The expression is mild, or perhaps more than mild to those who consider this perhaps not mild, a symbolic gesture of frustration..
Oh for Pete's sake.. not that I have anything against anyone called Pete or intending to call anyone Pete.
My point if this.. some people make it hard to express an opinion when everyone's opinion/perspective/beliefs have to be taken in respect.....it's called "setting people up to fail".
As the caption says.... WTF?
