Why are people so obsessed by doing things the 'proper' way, rather than the way they prefer?
Whether I have butter onBread, with or without cheese is a matter of personal preference and how I feel on the day, the type of cheese, the type of bread and the quality of the butter.
Personally I prefer cheese on its own without bread, butter, biscuits, fruit, chutney and all the other various things that so often clutter a cheese board. Other people round me can eat as they like. I will stick to the cheese and to hell with all the rest.
