I write, eat, play pool, use scissors, swing a tennis racket, and probably other things, left handed...but I bat a ball, throw a ball, catch a ball, and use the mouse right handed...
When my firstborn child wanted to learn how to tie his shoes, I showed him how to tie a bow...he just could not get it, was getting frustrated, started crying, and I began to think he was either just slow on this, or not paying attention...then he said, it seemed backwards to him...and it dawned on me, that perhaps he needed to see a right handed person tie a bow...my hubby, who is right handed, was not at home, so I went to my neighbor, who was right handed and after she showed him one time how to tie a bow, he had it nailed down perfect...so when it came time for the younger boy to learn how to tie his shoes, I gave that job to his older brother...
When I first learned how to write cursive, I wrote what they call 'backhanded', that is, instead of my writing slanting to the right, it slanted to the left...the teachers could not stand it, and demanded that I write slanting to the right...to this day, I write slanting to the right....but if I am in a hurry, I revert back to my 'backhanded' ways...And I have to remind myself to write slanting to the right, its not a natural process...
Being left handed has never really been much of an inconvenience for me, altho I hate it when anyone hands me a charge card receipt to sign, or the Mailman has me sign for something...because they always present it to you as if you are right handed, and you must always turn it around...not a biggie mind you, but it just shows that they assume everyone is righthanded, when they are not...
The other inconvenience is whenever we go out in a group to a restaurant and sit at a booth...I must always sit on the outside because I eat left handed, and sitting next to a right handed eater, our arms always bump...
I don't really notice my being left handed as a handicap until I try to either mimic somebody's motions, or am presented with something like a top-bound binder. Those are really aggravating. And I can't write on a chalkboard very legibly.
You can always tell a lefty from a righty by looking at their hands - we always have ink or pencil smudges from going over our writing. Unless of course, I'm being creative and writing either backwards or with the paper nearly upside down.
Oh, I have a question - is the dominant hand supposed to be bigger than the other? I heard that somewhere, but my left hand is actually a bit smaller than my right.
