Just one question...

How can guys watch a movie, like, once and still remember every single line? Yet girls can watch a movie, like, a million times and remember maybe two or three major quotes and the colour of the main protagonist's shoes, but nothing more significant than that? Is this a genetic difference designed to make men remember more things? And if so, why can't they remember their mum's birthday, but they can recall every set of weekly football results for their local pub team from the year of it's inception, in 1802? In fact, why are their memory skills reserved purely for useless facts such as world cup results and movie scripts, rather than anything useful or practical such as, say, shopping lists or things that are really really important and vital to do ASAP. Is it just that we girls are merely designed to remember vital dates and times, and our role on this earth is to remind our good men-folk about their duties as and when required? Or are we girls actually designed to remember the colour of the main protagonist's shoes and dress style just so we can go shopping later and get the exact same match for half the price in the sales?
