I eat with my fork in my right hand and my knife in my left hand.
I have always done this. I am not left-handed and have lost count of the number of people who have asked me if I am. It just feels easier for me. DH is the same.
Seriously - would you judge me and think I had bad table manners over this? AIBU to think people should use their cutlery whichever way round is comfortable?
