Haha, entirely loved reading this post.

If I started with noteworthy differences between my boyfriend and I, the list would never end! But the one thing that stands out is this - he always expects the answer to 'How big is the city?' in terms of population. I tend to use well known cities as a unit of measurement. So I would say 'half the size of Bombay'. In any case, I use geographical limits to gauge the size of a city.

It always baffles him how I don't know the population of each city I've visited. I think it's impossible to remember if it's 12 million or 18 million or 1 billion or 50,000.
