Why wrap it in a napkin to eat in the lounge???
Food is eaten at the table with a plate and a knife and fork.
My grandson's mother has terrible table manners (separated from my son long ago), doesn't use cutlery properly, and eats at break neck speed. Son and I knew that we would be the ones to teach grandson how to use a knife and fork.
We always eat at the kitchen table, discussing what we've done, plan to do etc. Grandson can now sit properly at the table, using the knife and fork properly, and we always include him in conversations. We can now take him anywhere knowing he will never embarrass us, and can talk with adults politely. These are surely all vital skills for anyone?
