Right handed

While I was embroidering I noticed something. I was stitching with my right hand.  I am left handed, but throughout life have found myself occasionally doing things with the other one.  I have always cut right handed, but I attribute that to the lack of left-handed scissors available in school.  I write and crochet left handed, but use the mouse right handed, and now, apparently, I also do hand stitching that way.

I noticed in the fall when I was painting our porch that I switched back and forth depending on what side of the ladder I needed to reach.  Does everyone perform tasks with different hands? Is it a left-handed issue from living in a right-handed world? Or is it just me?

Just a glimpse into what runs through my mind when I am working on a project.
