What wrong with this picture? Yes, the napkin is in the wrong place, it belongs under the fork on the left. And I have no idea what is in the wine glass.
Just make it look nice and always have enough food and drink. We never use paper napkins (but that’s just me), but a napkin of any kind is absolutely a necessity; even in a picnic basket. It also does not matter what kind of dishes, you have, it is just really nice to set the table for dinner. I think the food always taste better with a nicely set table. Shut off the TV, no phones, text, iPad, maybe turn on some nice music. Enjoy, your food, maybe chat a bit, just have some Fun. Remember, Life is a Banquet and Most Poor Suckers are Starving!
