Another left hander here!
Well, sort of. I write with my left hand, but do just about everything else with my right. A few things I can do with either.
My son is strongly left handed, does everythnig with left, and left footed too. Doesnt change cutlery around though. Exactly the same as my husband.
My daughter is right handed, does absolutely everything right handed - except she is the only one in the family who does change her cutlery around!!!
I have always thought there is far too much made of whether someone is right or left handed. After all, people are (more or less!) symmetrical to look at, its not as if hands are positioned centrally and so using one strangely out to the side on the left would be "awkward". It is no more or less awkward than using one positoned out to the right, for most things.
Just a few things specifically designed for right handers may be awkward. I remember when my son was quite a small baby (I know people say that no preference is shown for one hand or the other till later on, but I disagree) he had a toy when you had to press down a lever and a door opened and an animal popped out, only it was designed with the door to the left of the lever, so when he did it, always using his left hand, the door would never open properly as his hand was in the way when holding the lever! I always intended to write to Fisher Price, but never got round it!
