I eat crustaceans and some fish whole where applicable. Shell and all.

I divide rice plates into rows and eat it like a dot matrix printer.

I never use my left hand while eating. It literally stays behind my back while I eat right handed. No idea why although I hear that my late grandfather used to do that too.

Lol I love the dot matrix imagery.

It may be totally unrelated to your family, but depending on your cultural background, only eating with your right hand is pretty common across the Middle East. I believe it’s because the left hand is usually associated with wiping your bum, so it was best to keep that hand away from your food. Some folks can actually get a little offended/weirded out if you eat with your left hand at their table. I love these little cultural anecdotes.
