I'm a lefty but do everything else with my right hand. My earliest memory of using lefty scissors was in 5th grade and they were metal and super uncomfortable to use. Meanwhile, the other kids were given modern scissors with the hard plastic molding. I don't remember if I felt discomfort with those but I sure didn't want to use old rusty scissors so I stuck with it.
I kick with my left foot too. I feel more comfortable throwing with my right. If I'm holding a bat, I do so the "normal" way (idk terminology there).
When my son was learning to write I was super excited that it looked like he would be a lefty but a week later he favored his right hand for scribbling.
Exactly the same for me. I am very used to using my right hand so most thing I can do with both hands. When I played baseball (Even though I am Dutch) I could swing with my left and my right. I do catch with left though.
Weird thing is; lefties are rare. I have a very old group of friend that I know since I was 15. We are all lefties and one friend even married a left handed woman so the lefties are in the majority.
