The next recollection of left-handed discrimination was when my 1st grade teacher forced me to conform to traditional penmanship style - resulting in the contorted writing form most left-handers adopt.
As I moved in to High School I also had to contend with desks designed for right-handers. Not a single fricking desk with the arm on the left side.
Let's face it. The world is pretty much designed for right-handed people!!!
Every time I fire up my edger I think - why in the H E double tooth picks can't they make a left-handed weed whacker? You righties hold the trimmer in your right hand and the clockwise motion of the head slings the debris away from you. We lefties hold it in our left hand (at least we'd like to) and as a result, we get pummeled by grass, dirt, gravel, etc. shot out ankle high. Not only is it irritating, it's down-right painful. I've come away with some pretty serious dings and cuts from trimming in "rough" areas.
Seems like some equipment manufacturer would recognize the problem and do something about it. But then again, I thought the same thing about the desks in High School.
The solution, of course, is NOT to hold the trimmer in my left hand. But just like a baseball bat - it's hard to change old habits.
