Reading through this conversation 9 years in the future is absolutely hilarious! Sadly, the English language cares little for the opinions of a handful of pedants and continues to evolve with utter disregard of those who try to stop it. 'Their', 'they' and 'them' are now in common usage when referring to a singular person of unknown gender, while the default 'his', 'he', 'him' has pretty much died a death. Poor D.A.W.
