My wife sometimes cuts all her food up before starting, so she can just use the fork to shovel it in.
Find it really odd when people cut food up and then switch the fork to the other hand tbh. Savages.
Maybe as a lefty I’m just more used to doing things with both hands? Fork left, knife right always. Never crossed my mind to cut with my left hand. Also never crossed my mind to use a computer mouse with my left hand. Beauty of that is I can write and point click click at the same time. Just don’t ask me to write with my right hand.
