Wondering if anyone else is like me

I am a lefty, but only for specific tasks. I write left handed, I paint left handed, I draw left handed; anything that requires a decent amount of fine dexterity is.done left handed. Thay being said, I am right hand dominant with everything else, throwing a ball, playing guitar, shooting, boxing, etc. My mother was a lefty and she is the one that raised me for the first 10 years of my life. I cant help but wonder if she just naturally taught me to hold a pen/pencil and write left handed when I was meant to be right handed. Anyone else have a similar kind of thing going on?
