Now we've had a philosophy which has worked over the years.
Never get into who had the extra beer or side dish in the restaurant.
Or who bought one more round in the pub.
Share the bills equally, unless someone regularly takes the p iss.
Because if you think about it, over time it all works out pretty even.
And if you were all living together as we are 'virtually' at the moment we would be sharing anyway.
Plus it saves a lot of arguments!
(Excessive demands for caviar and Dom Pérignon excluded from this theory)
Of course it only works with a close family and true friends!
